Srabanti Chaudhury

Associate Professor


Chemical physics, theoretical biophysics


Srabanti Chaudhury obtained her PhD degree in 2009 in Theoretical Physical Chemistry from IISc Bangalore. She was a postdoctoral fellow at Rice University, The University of Texas at Austin and the Los Alamos National Laboratory before joining IISER Pune in 2013.


Theoretical biophysics, chemical physics

Dr. Srabanti Chaudhury uses methods of statistical mechanics and stochastic processes to study problems in chemical/biological physics, and soft condensed matter. At the theoretical level, the group develops analytical models to understand physiochemical processes where stochasticity and randomness play an important role. Further, they develop mathematical techniques and theoretical models to probe stochasticity that is inherent in the dynamics of such physiochemical processes. The group's analytical work is complemented with numerical simulations and experimental inputs.There are a few main research directions in the group: Single molecule enzyme catalysis, single molecule heterogeneous nanocatalysis, exploring timescales in reaction dynamics, DNA-protein recognition, polymer physics, conformational studies of charged polyelectrolytes and many more.
