Research Interests
I am a theoretical statistical physicist. My research focuses on polymer dynamics theory, pattern formation dynamics and biophysics. Most recently I have studied the role of reactions in stabilizing polymer interfaces, the formation of domains after quenches into thermodynamically unstable regions and motion of vesicles in nerve synapses.
