Roger Wartell received his B.S. degree in Physics from Stevens Institute of Technology in 1966. In 1971, he received his Ph.D. in Physics from the University of Rochester where he worked in the group of Elliot Montroll on the DNA helix-coil transition. From 1971-1973 he was a NIH postdoctoral fellow in the laboratory of Robert Wells at the University of Wisconsin-Madison. He was a Visiting Professor at the University of Wisconsin-Madison in 1978-79, and Visiting Scholar at National Institutes of Health-Bethesda from 1987-88. 

Wartell joined the faculty at Georgia Tech in 1974. Roger received a NIH Career Development Award in 1979 and served as Associate Chair in School of Physics from 1987-88, and Chair of the School of Biology from 1990-2004. He is a member of the NASA Astrobiology Institute at Georgia Tech. His current research is focused on protein-RNA interactions relating to sRNA regulation in bacteria, and the assembly and reactions of small RNAs in ice.

T. Richard Nichols received the B.S. degree in biology from Brown University, Providence, RI, USA, in 1969, and the Ph.D. degree in physiology from Harvard University, Cambridge, MA, USA, in 1974. He is currently a Professor in the School of Biological Sciences at the Georgia Institute of Technology.,He is currently a Professor in the School of Biological Sciences at the Georgia Institute of Technology, Atlanta, GA, USA.

Frank Rosenzweig is a Professor in School of Biological Sciences. He holds Bachelors degrees in Comparative Literature and Zoology from University of Tennessee-Knoxville, and a PhD in Biology at University of Pennsylvania. He carried out postdoctoral studies at the University of Michigan. He was a professor at University of Idaho, University of Florida, and University of Montana before joining the Georgia Tech faculty in 2016. He served as the Director of the NASA Astrobiology Institute funded center “Reliving the Past” from 2015 to 2019.  His research group studies the ecological and evolutionary forces that produce and preserve genetic variation using experimental evolution  to illuminate how genetic variation maps onto organismal fitness.

I graduated in Biological Sciences (B.Sc, University of Salford, 1997) prior to undertaking a Ph.D in molecular microbiology studying quorum sensing in Pseudomonas aeruginosa (University of Nottingham, 2001). I worked as a Postdoctoral Fellow at Nottingham on both EU and BBSRC funded grants, before obtaining a Royal Society University Fellowship (2006-2014). I was promoted to Associate Professor in 2013. In 2017 I moved as an Associate Professor to the School of Biological Sciences at Georgia Tech. I was promoted to Full Professor in 2022. I was appointed as the Director of the Center for Microbial Dynamics and Infection in January 2023. 

I currently serve as the Deputy Editor in Chief of Microbiology, where I have previously served as editor and senior editor. I have also previously served on the editorial boards of FEMS Microbiology Letters, BMC Microbiology, Microbiology Open and Royal Society Open Science. I was an elected member of the Microbiology Society Council (2012-2016) and also served on their conference and policy committees. I was selected to be an American Society for Microbiology Distinguished Lecturer (2021-2023) and was elected to the American Academy of Microbiology in 2023. 

In my spare time I play bass guitar. I recorded some original music in a band called Meaner and I currently play in a covers band called The Variants of Concern. I also have a long-standing interest in the works of J.R.R. Tolkien.

Ingeborg Schmidt-Krey is an associate professor in the School of Biological Sciences at Georgia Tech. Her research interests lie in the structure and function of eukaryotic membrane proteins, two-dimensional crystallization, electron crystallography, single particle analysis, and electron cryo-microscopy (cryo-EM).

Dr. Jang’s lab uses multi-disciplinary approaches to study muscle stem cell biology and develops bioactive stem cell delivery vehicles for use in regenerative medicine. Dr. Jang’s lab studies both basic aspects of muscle stem cell biology, especially systemic/metabolic regulations of stem cell and stem cell niche, as well as more translational aspects of muscle stem cell and mesenchymal stem cell for use in therapeutic approaches for musculoskeletal aging, neuromuscular diseases, and traumatic injuries.

Terry Snell, an Emeritus Professor in the School of Biological Sciences, is a member of the Parker H. Petit Institute for Bioengineering and Bioscience.

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.

Roman Mezencev is an adjunct associate professor in the School of Biological Sciences at Georgia Tech and a scientist at the U.S. EPA’s National Center of Public Health and Environmental Assessment. His areas of research interest include cancer biology, pharmacology, toxicogenomics, protein misfolding diseases, and public health. In cancer biology, his main research focuses on using omics data to identify new cancer subtypes through molecular profiling, which can help enhance their diagnosis and treatment. Additionally, Mezencev explores the use of omics data to predict and understand chemically-induced cancer and other adverse outcomes to protect public health. He is also investigating the intriguing epidemiological associations and mechanistic connections between cancer and Alzheimer’s disease (AD), as well as other protein-misfolding diseases. By understanding these associations, we can identify shared risk factors and molecular mechanisms that can lead to the development of new anti-cancer and anti-AD drugs and enhance our understanding of these complex diseases.
