Postdoctoral fellow / Evolutionary systems biology     e-mail: pavithra.venkataraman.1 [at] ulaval.ca

Biography

I was born and brought up in Bangalore, India. Towards the end of my Bachelors in Chemical Engineering at M. S. Ramaiah Institute of Technology, I became interested in studying biological systems using mathematical approaches. So I joined Indian Institute of Technology Bombay, Mumbai for a PhD. My thesis work focused on understanding the mechanisms and dynamics of genetic adaptive evolutionary processes, using both theory and experiments. During my PhD, I also spent a year as a Fulbright-Nehru Scholar at the University of California, San Diego, working on understanding the rigidity of fitness landscapes. In March 2025, I joined Landry lab as a postdoctoral fellow to work on protein evolution.

Research interests

My broad research interest is adaptation. In Landry lab, I am studying epistasis between regulatory and coding regions mutations, and how this interplay facilitates or constrains evolution. I am also interested in using computational approaches to understand protein evolution.
