Research Description:
The core focus of my research program is to understand the interactions and mechanisms underlying the behaviour of various physiological systems using mathematical and computational approaches. I use these approaches to (i) provide important insights into the cellular and molecular processes regulating these systems; (ii) test experimental hypotheses; (iii) identify targets to manipulate their dynamics; (iv) determine the causes of abnormalities exhibited by them; and (v) ultimately develop technological tools to decipher their kinetics. The mathematical models that emerge from these studies raise intriguing mathematical questions that I then analyze either numerically, using computational tools, or theoretically, using methods of nonlinear and stochastic dynamics. This work is conducted in close collaboration with several renowned national and international experimental laboratories. For more details, please visit:听
