After completing my graduation in Physics ( Fatima Mata College, Kollam), I joined Institute of Mathematical Sciences, Chennai where I did my M.Sc and later, Ph.D. I spent the next few years engaged in post-doctoral research, first at the Department of Physics, Virginia Tech and later at MPI-PKS, Dresden. I was a member of the faculty at Harish-Chandra Research Institute, Allahabad for a few years before joining IITM in December 2008.
In a nutshell, using statistical physics to understand the working of the biological cell is the underlying theme in my research. Over the years, my work has touched upon lipid rafts, physics of olfaction, chemotaxis in bacteria and eukaryotes, motor proteins and dynamics of microtubule filaments.
Current research interests include
- Noise in intracellular processes, and its role in cell motility - chemotaxis
- Dynamics of microtubules and collective force generation by intracellular filaments
- Stochastic dynamics of motor proteins- collective effects and tug-of-war
- Memory in intracellular transport
- Diffusive interaction in filament bundles and collections of cells
- Anomalous diffusion of randomly migrating cells
