Welcome to the virtual home of the Iyer-Biswas laboratory, located in the
Department of Physics, Purdue University. To learn more about the PI, please visit the Group page.

Discovering physical principles that govern stochastic single-cell behavior, and transcend the details of specific biological systems, is the primary focus of our research. In recent works (using
experiments and theory), we have found the scaling laws governing the stochastic growth and division of individual cells under steady-state growth conditions. To continue to explore what we do, please visit our Research page.
