Bhargav Ram Karamched

Biomathematics, Biophysics, and Bioengineering

I am an Associate Professor at Florida State University in the Department of Mathematics and the Institute of Molecular Biophysics. I am interested in a number of topics in applied mathematics, specifically involving applications of the theory of dynamical systems, partial and stochastic differential equations, and nonequilibrium statistical physics to problems in cell biology, synthetic biology, physiology, collective behavior, and decision making.
