Dr. Krishna Swamy is an Assistant Professor at the Division of Biological and Life sciences, Ahmedabad University. He has had an exciting multi-disciplinary trajectory during his career. He holds a Masters in Physics from Pune University. He started his research career in biology at Molecular Biophysics Unit, IISc, where he developed algorithms for protein structure and function prediction. He then did his PhD in computational biology at the Institute of Information Science, Academia Sinica, Taiwan in 2012. During his PhD, he developed methods to quantify the influence of cellular factors, such as nucleosomes, on the evolution of transcriptional control sequences. He also studied the confluence between sequence evolution and functional evolution of such non-coding sequences in Yeast, Drosophila, and Primates. He transitioned into an experimental biologist at the Institute of Molecular Biology, Academia Sinica, Taiwan after receiving the prestigious Academia Sinica Distinguished Postdoctoral Fellowship, and worked on deciphering the molecular mechanisms underlying speciation, the evolution of complex traits such as fermentation and stress response and evolution of co-operation.

Krishna is interested in combining theoretical and experimental approaches to uncover the general principles underlying the evolution of novel phenotypes, and how these affect the fitness of the organism across various environments. His lab will approach this problem by performing experimental evolution in microorganisms such as E. coli, S. cerevisiae, and hybrids of S. cerevisiae and other related yeasts in a variety of laboratory environments and mathematical modeling. The goal is to identify the key changes in the genetic program that lead to the organism's adaptation to various stresses, and predict from first principles how such mutations can lead to new phenotypes. Krishna is also interested in developing methods to infer the evolutionary history of the emergence of new phenotypes from genomic and transcriptomic data.
