I'm an Assistant Professor at Rutgers University in the Department of Genetics.
Born and raised in India, as per cultural norm, I became an engineer/technologist. I received my undergraduate degree in Biotechnology from Anna University (pronounced un-nah).
I then received Ph.D. in Ecology and Evolutionary Biology from University of Tennessee, Knoxville, advised by Mike Gilchrist. During this time, I built models to understand the evolution of codon usage patterns.
I then did a postdoc with Josh Plotkin at University of Pennsylvania, where I worked on whole-cell models of protein translation, the role of epistasis in protein evolution, built codon substitution models, and methods for identifying rate variation in phylogenetic trees.
