She was a postdoctoral fellow at the Princeton Center for Theoretical Sciences and in the Applied Mathematics group and Harvard University. She is a professor in the School of Physics at the Georgia Institute of Technology. She uses differential geometry, knot theory, and geometric topology to understand the geometry of materials and their mechanical properties. She is passionate about using textiles, 3D printing, and virtual reality to teach geometry and topology to the public.

Our work focuses on how the brain decides which action to perform at each moment in time – that is, action selection. We are interested in the cortical and subcortical circuits that mediate this process, and how they go awry in neurological disorders such as Parkinson’s disease. Specifically, we perform measurements of large-populations of neural activity in freely behaving mice using imaging and physiology, and distill their behavior in real-time using 3D cameras and probabilistic approaches to machine learning. Additionally, we are pursuing new methods to control activity in these circuits using precision closed-loop deep brain stimulation.

Dr. Susan S. Margulies leads the U.S. National Science Foundation’s Directorate for Engineering in its mission to transform our world for a better tomorrow by driving discovery, inspiring innovation, enriching education, and accelerating access. With an annual budget of nearly $800 million, the NSF’s Engineering Directorate provides over 40 percent of federal funding for fundamental research in engineering at academic institutions, and it distributes more than 1500 awards supporting research and education each year. Projects funded by the Engineering Directorate span frontier research to generate new knowledge, problem-driven research to identify new solutions to societal challenges, and application-driven research to translate discoveries to uses that benefit society.

In partnership with industry and communities across the nation, the NSF’s investments in engineering research and education lead to innovative technologies and sustainable impacts in health, agriculture, clean energy and water, resilient infrastructure, advanced manufacturing and communication systems, and many other areas. NSF support also builds the Nation’s workforce capacity in engineering and supports the diversity and inclusion of engineers at all career stages. Together, the NSF’s investments in engineering research and education enhance prosperity, equity and quality of life for all Americans.

Margulies joined the NSF as the assistant director for the Directorate for Engineering in August 2021 after leading the Wallace H. Coulter Department of Biomedical Engineering at the Georgia Institute of Technology and Emory University. While on detail at the NSF, she is a professor and Georgia Research Alliance Eminent Scholar at Georgia Tech and Emory. She received her B.S.E. in mechanical and aerospace engineering at Princeton University, her Ph.D. in bioengineering from the University of Pennsylvania, and post-doctoral training at the Mayo Clinic. She joined the faculty at the University of Pennsylvania in 1993 as an assistant professor, rising through the ranks to professor. In 2017 she became the first faculty member tenured in both the Georgia Institute of Technology and Emory University, and she was a department chair in both the college of engineering at Georgia Tech and Emory’s school of medicine. 

Margulies is internationally recognized for pioneering studies spanning the micro-to-macro scales and across species to identify mechanisms underlying brain injuries in children and adolescents and lung injuries associated with mechanical ventilation, leading to improved injury prevention, diagnosis and treatments. She has launched numerous training and mentorship programs for students and faculty, created institute-wide initiatives to enhance diversity and inclusion, and led innovative projects in engineering education. 

Margulies’ transdisciplinary scholarly impact has been recognized by her election as fellow of the American Society of Mechanical Engineers, the Biomedical Engineering Society, and the American Institute for Medical and Biological Engineering, and as a member of the National Academy of Engineering and the National Academy of Medicine.  

Sakis Mantalaris is currently Professor in Biomedical Engineering at Georgia Tech & Emory. Prior he was Professor in Chemical Engineering at Imperial College London.

David G. Lynn has contributed in the general areas of molecular recognition, synthetic biology and chemical evolution, and has developed chemical and physical methods for the analysis of supramolecular self-assemblies, of signal transduction in cellular development and pathogenesis, of molecular skeletons for storing and reading information, and of the evolution of biological order.

Lynn has earned a Howard Hughes Medical Institute Professorship, the Emory Scholar-Teacher Award, a fellowship from the American Association for the Advancement of Science, and the ACS Charles H. Herty Medal.

During his tenure as Chair of the Department of Chemistry from 2006-2015, Lynn assisted in the renovation of the Atwood chemistry building. In 2018 and 2019, Lynn also served as a board member for the Atlanta Science Festival.

Hang Lu received her B.S. from the University of Illinois, Urbana-Champaign and her M.S.C.E.P and Ph.D. from the Massachusetts Institute of Technology. She is currently the Associate Dean for Research and Innovation in the College of Engineering and C. J. "Pete" Silas Chair, School of Chemical & Biomolecular Engineering at the Georgia Institute of Technology. Lu's research interests involve the interface of engineering and biology and her lab, the Lu Fluidics Group, is conducting research at these interface levels. The Lu Fluidics Group engineers BioMEMS (Bio Micro-Electro-Mechanical System) and microfluidic devices to address questions in neuroscience, cell biology, and biotechnology that are difficult to answer using conventional techniques.

My laboratory investigates molecular mechanisms underlying eukaryotic genome stability. Chromosomal rearrangements create genetic variation that can have deleterious or advantageous consequences. Karyotypic abnormalities are a hallmark of many tumors and hereditary diseases in humans. Chromosome rearrangements can also be a part of the programmed genetic modifications during cellular differentiation and development. In addition, gross DNA rearrangements play a major role in the chromosome evolution of eukaryotic organisms. Therefore, elucidation of molecular mechanisms leading to chromosome instability is important for studying human pathology and also for our understanding of the fundamental processes that determine the architecture and dynamics of eukaryotic genomes. 

My overall contribution to the field of genome instability has been the demonstration of the phenomenon that repeats often found in eukaryotic genomes are potent sources of genome instability. Specifically, I have been investigating one of the most fundamental and enigmatic processes as to how repetitive sequences that adopt non-canonical DNA secondary structures, such as hairpins and cruciforms, cause replication arrest, double-strand breaks, and gross chromosomal rearrangements. Using molecular biology approaches, we investigate the instability of secondary structure-forming repeats in Saccharomyces cerevisiae, Schizosaccharomyces pombe, and human fibroblasts.
