The College of Sciences feted new colleagues joining in the 2017-18 academic year at a summer dinner on Sept. 6. Dean and Sutherland Chair Paul M. Goldbart and Jenny Singleton, associate chair and professor in the School of Psychology, hosted the celebration, which also recognized recipients of 2017 College of Sciences awards.

“It is invigorating to start the school year by warmly welcoming new colleagues into our scholarly community and celebrating our outstanding teachers, researchers, and mentors,” Goldbart said.

One program director, one professor of practice, eight assistant professors, two associate professors, and three professors joined the college in the 2017-18 academic year. Three of them – Felix Herrmann, Gregory Sawicki, and Carlos Silva – have joint appointments in other Georgia Tech units.

The Schools of Biological Sciences and of Chemistry and Biochemistry welcomed the most number of new colleagues in the 2017-18 academic year – four each.

The Center for Education Integrating Science, Mathematics, and Computing (CEISMC) recruited Casey Bethel, Georgia’s 2017 Teacher of the Year, to coordinate campus communications.

Also celebrated as new colleagues were Rachel Kuske and Jenny McGuire. Kuske is a professor in and the chair of the School of Mathematics. She joined the College of Sciences on Jan. 3, 2017. McGuire previously held the position of Research Scientist II in the School of Biological Sciences. She is now assistant professor, tenure track, with joint appointment in the Schools of Biological Sciences and of Earth and Atmospheric Sciences.

Also at the 2017 summer dinner, nine faculty members were named recipients of 2017 faculty awards.

School of Mathematics Professors John Etnyre and Ronghua Pan, with School of Chemistry and Biochemistry Associate Professor Raquel Lieberman, received the 2017 College of Sciences Faculty Mentor Awards. They were recognized for sharing their experience, providing advice and encouragement, and helping the next generation of faculty succeed.

The college selected School of Physics Professor and Chair Pablo Laguna for the 2017 Ralph and Jewel Gretzinger Moving Forward School Award. The award praises leadership of a school chair or senior faculty member who has played a pivotal role in diversifying faculty, creating a family-friendly work environment, or providing a supportive environment for junior faculty. Laguna was commended for driving equity and inclusion and for mentoring of groups underrepresented in science, technology, engineering, and mathematics (STEM). The award is supported by an endowment fund from School of Mathematics alumnus Ralph Gretzinger.

School of Earth and Atmospheric Sciences Assistant Professors Chris Reinhard and Britney Schmidt received the 2017 Eric R. Immel Memorial Award for Excellence in Teaching. The award salutes exemplary teaching of a foundational class by junior faculty. In particular, Reinhard and Schmidt were commended for “their imaginative and effective redevelopment” of EAS 1601, How to Build a Habitable Planet. Their work has inspired teaching assistants, excited students, and raised enrolment. The award is supported by an endowment fund from School of Mathematics alumnus Charles Crawford.

School of Physics Assistant Professor James “JC” Gumbart, School of Biological Sciences Associate Professor Brian Hammer, and School of Mathematics Associate Professor Anton Leykin were recognized with 2017 Cullen-Peck Fellowship Awards. The awards recognize innovative research led by faculty who are at the associate professor or advanced assistant professor level. They are made possible by a gift from School of Mathematics and School of Industrial and Systems Engineering alumni Frank Cullen and Libby Peck. The awards applaud outstanding research in computational biophysics (Gumbart), in the biology of competition and cooperation in bacterial systems (Hammer), and in applied and computational algebraic geometry (Leykin). 

“We are proud to have so many exceptional faculty members,” Goldbart said. “I am especially grateful for the generosity of our thoughtful alumni, whose gifts enable our colleagues to achieve the highest level of success in their teaching, research, and service.”

There is a genomic revolution happening across the planet, as researchers apply genome science and related technologies to advance the understanding of health and disease in different populations, identifying those who are at risk due to genetic and/or environmental factors for developing specific diseases.

It’s a scattered and somewhat inconsistent revolution, however, as some regions with adequate resources set the pace for discovery, while others are left virtually stranded. Such is the case on the African continent, where many countries are being left behind, a situation that has the potential of widening global and ethnic inequalities in health and economic well-being.

Fortunately, though, a collection of individuals and institutions, including the Georgia Institute of Technology, are responding to the challenge and working to bridge the genomic divide. It’s the kind of bridge-building that King Jordan, a researcher with the Petit Institute for Bioengineering and Bioscience, has grown accustomed to. His lab, and the Bioinformatics Graduate Program that Jordan directs, have been deeply engaged in biotechnology capacity-building efforts in Latin America for close to a decade.

“We’re leveraging bioinformatics and genomics technologies to facilitate public health and to stimulate economic development overseas,” says Jordan, associate professor in the School of Biological Sciences, who cites the Georgia Tech strategic vision plan laid out in 2010, specifically goal number four, which involves expanding Tech’s global footprint and influence.

“That is done in two ways,” says Jordan. “One is by bringing the world to Georgia Tech and training more globally-engaged students. The other way is to project Georgia Tech’s reach out to the world, and we’re doing both.”

And now it’s happening in Africa, with the recent announcement that Jordan and one of his former grad students, Daudi Jjingo, have been awarded a five-year, $1.3 million grant as part of the NIH’s Human Heredity and Health in Africa (H3Africa) Initiative. H3Africa aims to elucidate Africa’s human genetic diversity (the highest on the planet) and thus one with a high potential of revealing more varied ways in which the human genome interacts with diseases and other environmental pertubations.

The plan is to use the award to support two trajectories, according to Jjingo, who earned his PhD as a Fulbright fellow in Jordan’s research team at Georgia Tech in 2013 and returned to his home country, Uganda, where he is a faculty researcher at Makerere University in Kampala.  

“First we want to focus on building a computing and physical infrastructure, and secondly, we want to actually start a bioinformatics program,” says Jjingo. “The idea is to build a sustainable bioinformatics program.”

There is a lot of clinical research happening now in Africa, Uganda in particular, Jjingo says, and researchers currently lack the bioinformatics resources to adequately analyze all of that data.

“So the vision is, at the end of five years we’ll have this program established, well-staffed, with students graduating,” Jjingo says. “Having talented students who graduate creates the infrastructure – it builds the right recipe to build a research center, which means we can move beyond academia and provide bioinformatics consulting services for industry and others.”  Their bioinformatics consulting efforts will be modeled after the Applied Bioinformatics Laboratory (ABiL), a public-private partnership between the Jordan lab at Georgia Tech and the company IHRC Inc., which provides bioinformatics analysis services and training to industry and non-profit clients.

The program in Uganda will begin, Jjingo says, “with about five Masters students and a couple of PhD students, and the plan is that one of them will spend a year at Georgia Tech – from my own experience, I know the huge value you can get by spending a short time there, learning from a mature research environment and ecosystem. And Georgia Tech personnel will come here to Uganda, to conduct short seminars, and so forth. So we’re talking about an exchange of human resources.”

Jordan adds, “one thing we know that is implicit in the notion of mentoring a grad student is the idea of collaborative research. So when you have a graduate student that serves as the fulcrum between two institutions, it provides a great opportunity build bridges. My hope is that those students will engage in collaborative research that will allow for deeper connections between Georgia Tech and Makerere University.”

Sand-swimming lizards, slithering robotic snakes, dusk-flying moths and running roaches all have one thing in common: They're increasingly being studied by physicists interested in understanding the shared strategies these creatures have developed to overcome the challenges of moving though their environments.

By analyzing the rules governing the locomotion of these creatures, "physics of living systems" researchers are learning how animals successfully negotiate unstable surfaces like wet sand, maintain rapid motion on flat surfaces using the advantageous mechanics of their bodies, and fly in ways that would never work for modern aircraft. The knowledge these researchers develop could be useful to the designers of robots and flying vehicles of all kinds.

“Locomotion is a very natural access point for understanding how biological systems interact with the world,” said Simon Sponberg, an assistant professor in the School of Physics and School of Biological Sciences at the Georgia Institute of Technology. “When they move, animals change the environment around them so they can push off from it and move through it in different ways. This capability is a defining feature of animals.”

Sponberg has spent his career bridging the gap between physics and organismal biology – the study of complex creatures. His work includes studying how hawk moths slow their nervous systems to maintain vision during low-light conditions, and how muscle is a versatile material able to change function from a brake to a motor or spring.

He recently published a feature article, the cover story for the September issue of the American Institute of Physics magazine Physics Today, on the role of physics in animal locomotion. The article was not intended as a review of the entire field, but rather to show how organismal physics – integrating complex physiological systems, the mechanics and the surrounding environment into a whole animal – has inspired his career.

“The intersection of physics and organismal biology is a very exciting one right now,” said Sponberg, who is also a researcher with the Petit Institute for Bioengineering and Bioscience at Georgia Tech said. “The assembly and interaction of multiple natural components manifests new behaviors and dynamics. The collection of these natural components manifests different patterns than the individual parts, and that’s fascinating.”

Supported by new initiatives at such organizations as the Army Research Office/Army Research Laboratory and the National Science Foundation – which are embracing these frontiers – Georgia Tech scientists are learning the equations that dictate how snakes move, understanding how the hair spacing on the bodies of bees help them stay clean, and using X-ray equipment to see how an unusual African lizard “swims” through dry sand.

“It’s a really exciting time to be working at the intersection of evolutionary organismal biology that is realized in these living systems that have come about through the process of evolution, composed of seemingly very complex systems,” he said. “Biological systems are inescapably complex, but that doesn’t mean there aren’t simple patterns of behavior that we can understand. We now have the modern tools, approaches and theory that we need to be able to extract physical patterns from biological systems.”

In his article, Sponberg makes predictions about the research that will be needed for the physics of living systems to advance as a field:

  • How feedback transforms physiological dynamics,
  • How aggregations of living components, from humans to ants to molecular motors, arise at multiple scales, and
  • How robo-physical models of these complex systems can lead to new discoveries and advance engineering.

Engineered systems use feedback about the effects of their actions to adjust their future activities, and animals do the same to control their movement. Scientists can manipulate this feedback to understand how complex systems are put together and use the feedback to design experiments rather than just analyzing what is there. 

“We use feedback all the time to move through our environment, and feedback is a really special thing that fundamentally affects how dynamics occur,” said Sponberg. “But using feedback to design experiments is really sort of new.”

For example, in the study of how hawk moths track flowers during low-light conditions, he and his colleagues used feedback dynamics to isolate how the moth’s brain adjusts its processing in dim light. The moths can still accurately track flower movements that occur less than two times per second – which matches the frequency at which the flowers sway in the wind.

Animals are composed of many systems operating at multiple time scales simultaneously – brain neurons, nerves and the individual fibers of muscles with molecular motors. These muscle fibers are arranged in an active crystalline lattice such that X-rays fired through them create a regular diffraction pattern. Understanding these multiscale living assemblages provides new insights into how animals manage complex actions.

Finally, Sponberg notes in his article that robots are playing a larger and larger role in the physics laboratory as functional models that can examine principles of movement by interacting with the real world. In the laboratory of Georgia Tech Associate Professor Dan Goldman – one of Sponberg’s colleagues – robotic snakes, turtles, crabs and other creatures help scientists understand what they’re observing in the natural world.

“Moving physical models – robots – can be very powerful tools for understanding these complex systems,” Sponberg said. “They can allow us to do experiments on robots that we couldn’t do on animals to see how they interact with complex environments. We can see what physics in these systems is essential to their behaviors.”

Sponberg was inspired to study the interaction of organismal biology and physics by the remarkable diversity of animal movement and by nonlinear dynamics, a field made popular when he was a young student by the 1987 best-selling book Chaos: Making a New Science, authored by former New York Times reporter James Gleick. Sponberg hopes today’s students – readers of Physics Today – will also be inspired.

“I voted on this with my career choice, so I think this is a very exciting areas of science,” he added.

Seven students have joined the Interdisciplinary Ph.D. program in Quantitative Biosciences (QBioS).  These students have backgrounds in physics, mathematics and biology and join the program from the United States, China, and India.  Altogether, the QBioS Ph.D. program now includes 16 students, including nine members from the inaugural cohort who joined in Fall 2016.  The QBioS Ph.D. is directed by Biological Sciences Professor Joshua S. Weitz.

The QBioS Ph.D. was established in 2015 and includes more than 50 program faculty. The mission of QBIoS is to educate students and advance research, enabling the discovery of scientific principles underlying the dynamics, structure, and function of living systems at scales from molecules to ecosystems.   Of the seven incoming students, four are affiliated with the School of Biological Sciences and three are affiliated with the School of Physics.

Kelimar Diaz Cruz obtained a B.S. in Physics from the University of Puerto Rico, Rio Piedras Campus in Puerto Rico this year, before joining the QBioS Ph.D. “Before my undergrad, I had no idea there were many branches of Physics,” Diaz notes.  “Once I learned Biophysics was one of them I immediately knew in what direction I wanted to head. The QBioS Ph.D. program will allow me to develop interdisciplinary and quantitative approaches for the understanding of biological systems. There is no better program that aligns with my interests. I am looking forward to expanding my knowledge of biological sciences as I work alongside faculty and researchers in different areas.”

Guanlin Li graduated with a B.S in Mathematics and Physics Minor in 2016 from Arizona State University and earned his M.S in Mathematics from Georgia Tech this year before transferring into QBioS. “I like to utilize mathematical and computational tools to answer fundamental questions raised in the biosciences,” Li says. “QBioS opens a new door that brings biosciences to a quantitative side, from experimental interpretations to equations and laws. I'm excited and looking forward to joining this new program.”

Daniel Muratore completed a Bachelor's in Biological Sciences at the University of Chicago in 2016, focusing primarily in theoretical ecology. After graduating, he worked in Maureen Coleman's lab at the University of Chicago on microbial ecology and biogeochemistry for marine and lake systems. Muratore moved from to Atlanta to work with Weitz on virus-host models and nutrient dynamics in marine ecosystems and to start his PhD in QBioS, explains, “I am very excited to use modeling approaches and robust analytical methods to handle a diversity of data coming from the worlds of oceanography, molecular biology, and bioinformatics for the purpose of generating new knowledge about the goings on of the marine microbial ecosystem.”

Brandon Pratt graduated from the University of Washington earlier this year, receiving Bachelor of Science degrees in neurobiology and in molecular, cellular, and developmental biology. He notes, “I was drawn to the PhD program in Quantitative Biosciences at Georgia Tech because of its unique design that bridges the gap between biosciences and engineering. Coming from a primarily biosciences background, this program allows me to expand my repertoire of technical skills and knowledge to include those from the fields of computer science and engineering. I aim to use these skills to better describe living systems, particularly neural systems.” Pratt intends to conduct research involving how sensory information is acquired, processed, and integrated in the nervous system.  

Kai Tong earned his B.S. in Biological Sciences from Fudan University in Shanghai, China, this year. Initially admitted into the Ph.D. program in Biology, Tong decided to transfer to QBioS. “I was amazed by the easy-going and collaborative atmosphere here," Tong says. “And equally importantly, the fit with my research interests in major evolutionary transitions and social evolution.” He noted that his training as a ‘traditional’ biologist involved a leap to transfer to QBioS. “This out-of-comfort-zone effort will allow me not only to use more quantitative toolkits to tackle biological questions, but also to test hypotheses or perform predictions that usual experimental methodology may not be able to, as well formulate insights into a more abstract and generalizable way.”

Akash Vardhan received his training in Production Engineering from Jadavpur University, India, graduating in 2013. After completing his undergraduate education, he worked as a vehicle dynamics test engineer in the automobile industry, before moving on to study the mechanics of bug flight in Sanjay Sane’s lab at the National Centre for Biological Sciences in Bangalore, India. “As a part of the QBioS program I would love to continue working on the biomechanics and control of locomotion in a wide variety of animals,” Vardhan says. “Form and function is another area that I find really fascinating, how seemingly simple interactions can give rise to an emergent behavior which is really complex has also gotten me really interested.”

Mengshi Zhang received her B.S. in Biotechnology from South University of Science and Technology of China in 2015 and then switched to the Department of Physics at the Chinese University of Hong Kong for her master’s degree (MPhil), graduating earlier this year. She is fascinated by the quantitative descriptions of biological phenomena and drawn to this interface in QBioS. Zhang has backgrounds in system biology and synthetic biology, and experience in wet and dry labs. “I would like to combine both computational analysis and experimental methods and look forward to integrating principles of physical, mathematical and biological science together within QBioS,” she says.

 

Georgia Institute of Technology researchers developed a novel approach to summarize disease risk, creating a score for an individual based on gene expression – transcriptional risk score (TRS). They’ve applied this score in a recent ground-breaking study, which accurately predicts complications in Crohn’s disease, and potentially paves the way for personalized medicine strategies in the future.

“We were testing an intuition,” says Urko Marigorta, lead author of the study, “Transcriptional Risk Scores link GWAS to eQTL and Predict Complications in Crohn’s Disease,” published in the journal Nature Genetics.

“We wanted to see if checking the actual expression of pathogenic genes involved in disease is better than just looking at an individual’s DNA when assessing the risk for disease,” adds Marigorta, a postdoctoral researcher in lab of Greg Gibson, professor in the School of Biological Sciences and a researcher in the Petit Institute for Bioengineering and Bioscience at Georgia Tech.

This was part of a multicenter research initiative, the Crohn’s & Colitis Foundation’s “RISK Stratification” study (the largest new-onset study of pediatric Crohn’s disease patients), and a follow-up to research published earlier this year in the journal, The Lancet.

That study, says Gibson, evaluated “whether anti-TNF treatment really is beneficial in reducing inflammation and preventing progression to complicated Crohn’s disease. It is, but apparently only for a subset of patients. Our contribution there was to show that this subset can, to some extent, be identified at diagnosis on the basis of their overall gene expression profile in the ileum.”

The Nature Genetics paper takes advantage of the data sets analyzed in the previously published research. The RISK Stratification Study involved 28 clinics and 1,800 pediatric patients – a good sample size, according to Marigorta, who adds, “most important, [we had] two forms of biological data: DNA and gene expression from the small intestine. Importantly, the gene expression from RISK was obtained at diagnosis, when kids went to the hospital and before developing complicated versions of Crohn’s disease.”

So basically, Marigorta and Gibson wanted to test their novel approach, TRS, against genetic risk scores (GRS), or scores based on an individual’s DNA, which is currently the dominant approach in the field. But predicting disease risk from just DNA is difficult.

“In the last few years we’ve learned about many genes that are associated with disease – genes that have mutations, that are more frequent in people with disease than in healthy people,” Marigorta says. “But many people with mutated genes do fine, whereas others without them end up getting sick with some disease. Most of the field is trying to discover more of these mutations, which is totally fine because that will tell us more about biology, and will make for good drug targets. But we’re not sure it will add that much in terms of prediction.”

Marigorta’s statistical and bioinformatics analyses of the genomic data demonstrated that their intuition was on target: gauging the expression of risk genes (TRS) does a better job of predicting complications of Crohn’s than just adding up the number of risk genes (GRS).

“So, instead of trying to predict how good a football team is going to be by adding up how many players make $10 million a year, we actually evaluate how well they are performing,” says Gibson, using a familiar sports analogy.

This paper published in Nature Genetics was a collaboration of 23 author/researchers from 18 institutions – two in Canada and 16 in the U.S., including Emory University’s School of Medicine. Emory physician/professor Subra Kugathasan, director of the Children’s Healthcare of Atlanta Combined Center for Pediatric Inflammatory Bowel Disease, shares senior authorship with Gibson (who was the corresponding author). Key leadership also came from co-authors Lee Denson (Cincinnati Children’s Hospital) and Jeff Hyams (Connecticut Children’s Medical Center)

Going forward, Marigorta sees two primary directions that the TRS research may take.

“We’d like to see if it works for other traits and we have evidence that it does, at least for autoimmune diseases such as juvenile arthritis,” he says. “And more importantly, we’d like to see if it works when using gene expression from blood draws. Imagine, down the road, if you could fine-tune the predictions of risk due to your DNA with information gained from looking at gene expression from a simple blood draw at your once-a-year checkup.”

Georgia Tech’s School of Mathematics is set to play an important role in the rapidly expanding field of data science, thanks to a National Science Foundation initiative that will fund foundational research and educational training on campus.

The new institute, the Transdisciplinary Research Institute for Advancing Data Science (TRIAD), is one of 12 national data science projects to receive $17.7 million in NSF funds, the agency recently announced. The School of Mathematics is one of six Tech schools taking part in TRIAD, which will receive $1.5 million of the NSF funding.

“The successful funding of the TRIAD partnership between the Colleges of Science, Computing, and Engineering recognizes Georgia Tech as a leader in the foundations of data science,” says School of Mathematics Professor and Chair Rachel Kuske. “We welcome the opportunities and challenges that come with this recognition. TRIAD will be an important base as our leadership in the mathematical and quantitative sciences continues to expand, addressing both fundamental and applied questions.”

Other schools participating in TRIAD are the H. Milton Stewart School of Industrial & Systems Engineering, the School of Electrical and Computer Engineering, the George W. Woodruff School of Mechanical Engineering, the School of Biological Sciences, the School of Computational Science and Engineering, and the School of Computer Science.

The rise of technology in everyday life has come with an increase in raw data generated by an ever-expanding number of connected devices. Media outlets are calling this information explosion “big data.” Companies, organizations, and governments are now on the hunt to find better ways of analyzing and modeling big data, with potential benefits for business, science, education, and law enforcement.

The NSF initiative Transdisciplinary Research in Principles of Data Science (TRIPODS) hopes to leverage academic expertise in mathematics, statistics, and theoretical computer science. In Phase I of TRIPODS, the NSF put out a call to support the development of small collaborative institutes. Georgia Tech responded with TRIAD, which will be operate alongside the recently launched Institute for Data Engineering and Science (IDEaS).  Xiaoming Huo, professor in the School of Industrial & Systems Engineering, will be TRIAD’S executive director; Prasad Tetali, professor in the School of Mathematics with a joint appointment in the School of Computer Science, will serve as co-principal investigator.

“The emphasis on theoretical foundations of data science offers a great opportunity for mathematicians to actively engage with other scientists and help make breakthroughs in this fast-growing interdisciplinary field,” says Tetali. “Our team also recognizes the importance of being the only team, out of the dozen winners of Phase I, to have been selected from the Southeast,” he added.

Faculty from the College of Sciences with expertise in algebraic and convex geometry, applied dynamics, computational and numerical methods, discrete mathematics, quantitative and computational biology, high-dimensional probability, and statistical inference will provide research for TRIAD. Faculty members include School of Biological Sciences Professor Joshua Weitz and School of Mathematics professors Leonid Bunimovich, Sung Ha Kang, Vladimir Koltchinskii, Rachel Kuske, Anton Leykin, Galyna Livshyts, Ionel Popescu and Mayya Zhilova.

 

Heart problems were much more common in the genes of our ancient ancestors than in ours today, according to a new study by geneticists at the Georgia Institute of Technology, who computationally compared genetic disease factors in modern humans with those of people through the millennia.

Overall, the news from the study is good. Evolution appears, through the ages, to have weeded out genetic influences that promote disease, while promulgating influences that protect from disease. But there's also a hint of bad news for us modern folks. That generally healthy trend might have reversed in the last 500 to 1,000 years. 

So, who appears to have had the healthier genes? The “cavemen?” We moderns? And who was more genetically susceptible to mental illness?

Shana Kerr must feel like she won the Triple Crown in 2017 – a baby in March and an advising award from Georgia Tech in April. Following soon after was an award from NACADA: The Global Community for Academic Advising, naming Kerr one of 10 winners of the association’s 2017 Outstanding Advising Award – Faculty Academic Advising.

Kerr is being recognized for her exemplary academic advising, which is based on giving students direction and resources so they can themselves discover the answers to their questions. She believes in being genuine in her interactions with advisees and learning as much from students as they do from her.

“When I joined the Tech community as a member of the teaching faculty, I never imagined that academic advising would become such a fulfilling aspect of my job,” Kerr says. “I am deeply honored to be recognized at the national level for my advising and extremely proud to represent Tech!”

Kerr joined the Georgia Tech faculty in 2012 as an academic professional in the School of Biological Sciences. Her primary role is teaching classes; along the way she got involved in advising students. She realized the importance and joy of student advising, and as her awards attest, she has become a top-notch academic advisor.

“Sometimes students want easy, direct answers,” Kerr says. “But students who are always given direct answers are not getting practice in answering questions for themselves. I might respond with, ‘Have a look at this website for information on this issue. Let me know if you run into trouble.’ Over time, I have found that this approach yields more sophisticated questions from the same student.”

Georgia Tech’s well-deserved reputation for rigor can be shocking to high-achieving new freshmen, some of whom may struggle to pass a class or likely fail. As an adviser, Kerr helps them develop not only study skills, but also the virtues of perseverance in the face of constant challenge and resolution not to give up. She uses her advising meetings to inquire about how students are doing, determine whether serious intervention is needed, and direct them to other resources. “Many students see these resources as a lifeline,” she says.

“Professionalism is important,” Kerr continues. “But we are all human, and humanity involves emotions, mistakes, and ultimately just being yourself.” Being genuine can mean a spontaneous hug when a student has accomplished a big goal, or empathizing with and even being frustrated on a student’s behalf when they have unhelpful encounters elsewhere. Kerr wants students to know that she is affirming their experiences.

“I am constantly humbled and inspired by the amazing students I work with,” Kerr says. “I have learned much about what it really means to be persistent in the face of unrelenting challenges. I am grateful to work with such motivated and hard-working students and so very pleased to have stumbled – accidentally and enthusiastically – into the critical role of academic advisor.”

EDITOR'S NOTE: This article was first published by the Ocean Science and Engineering Program on Aug. 9, 2017.

In November 2016, Georgia Tech launched the Ph.D. in Ocean Science and Engineering (OSE, www.ocean.gatech.edu), an interdisciplinary graduate program across the schools and faculty of Civil and Environmental Engineering (CEE), Biological Sciences (BIOL) and Earth & Atmospheric Sciences (EAS). Ten students make up the inaugural cohort, which will begin its studies in the 2017 Fall semester.

The OSE program has two goals:

  • to educate the next generation of transdisciplinary ocean scientists and engineers by combining basic and applied sciences with innovative ocean technologies
     
  • to advance interdisciplinary research at the frontiers of the physical, biological, chemical and human dimensions of ocean systems. 

The program attracted a diverse group of applicants interested in specializing in Ocean Technology, Ocean Sustainability, Marine Living Resources, Ocean and Climate, and Coastal Ocean Systems. Following are the members of the inaugural class, who will begin their studies in the Fall 2017 semester. Their orientation will take place on Aug. 14-18, 2017.

 

Alexandra Muscalus (OSE-CEE)

Alexandra Muscalus obtained a B.S. in Civil Engineering from Georgia Tech in 2016. She joins OSE with Georgia Tech Presidential and Institute Fellowships. Her research interests include ocean energy and fieldwork approaches to nature-based coastal resilience and shoreline change. She aspires to advance the field of coastal engineering as a professor. In her free time, Muscalus enjoys backpacking, scuba diving, playing musical instruments, running, and cooking.

 

Roth Conrad (OSE-BIOL)

Roth Conrad joins OSE with a Georgia Tech Presidential Fellowship. “I spent eight years traveling, exploring, and acquiring a diverse skill set and world view,” he says. “I worked on a sailboat in the Bahamas, which deeply affected my awareness of the environment.” Conrad also built and traveled across the country in a vegetable-oil-powered school bus, which inspired his fascination with microbiology and biological degradation. “Both experiences showed me how rewarding sharing ideas with people can be,” he says.

“My mind full of questions, appreciation for the environment, curiosity about microbes, and desire to share ideas are a few reasons why I am pursuing a Ph.D. in Ocean Science and Engineering at Georgia Tech.”

 

Abigail Johnson (OSE-EAS)

After receiving a bachelor’s degree in biology from Texas A&M University, Corpus Christi, and a master’s degree in biological and environmental sciences from the University of Rhode Island, Abigail Johnson looks forward to continuing her education in the OSE program. With this Ph.D.,  she says, 

“I hope to advance our tools in search for and our knowledge of Earth’s deep ocean life.”

Specifically, she plans to use a novel high-pressure chamber to characterize microbial communities in methane hydrates from the Gulf of Mexico incubated under in situ pressures. Upon receiving a Ph.D., she plans to continue her career in academia, with the goals of “researching the mysteries of our deep ocean and educating our future generations.”

 

Benjamin Hurwitz (OSE-CEE)

Benjamin Hurwitz is an electrical engineer from Brooklyn, N.Y. He graduated from Brooklyn Technical High School with a focus in chemistry before attending Colby College, in Maine, from where he graduated with a B.A. in Applied Mathematics. A long-time scuba diver, he spent a year in the Virgin Islands, teaching and guiding divers around the reefs. He returned to school at the University of Maryland, College Park, where he spent three years earning a B.S. in Electrical Engineering with a focus on microelectronics.

His interests include marine robotic electrical systems, instrumentation design, and integrated circuit fabrication.

When he’s not working, he can be found on the ice rink, in the climbing gym, or on the ocean.

 

Gian Giacomo Navarra (OSE-EAS)

Since high school Gian Giacomo Navarra was interested in astronomy and mathematics. He pursued a bachelor’s degree in theoretical physics at the University of Bologna, Italy. After an undergraduate research experience in the University of Bristol, he got interested and completed a master’s degree in condensed matter and statistical mechanics in 2016. After completing his thesis in computational mechanics, Navarra says,

“I realized that the methods I learned and developed in statistical mechanics have the potential to advance the geosciences, in particular ocean and climate dynamics (for example, El Niño), which have a high degree of stochastic physics.”

 

Melissa Ruszczyk (OSE-BIOL)
