Associate Professor


Statistical physics, soft condensed matter, phase transitions, microfluidics


Apratim Chatterji completed PhD from IISc in 2002, where he worked on developing models of self-assembling polymers. In 2002-2005, he was in Mainz-Germany developing multi-scale algorithms to investigate the electrophoresis of highly charged Brownian particles. After a brief stint in Uni-Toronto, he was in FZ-Juelich-Germany using multiscale-simulations to study shear of soft-particles. He joined IISER-Pune in 2009, and since 2017 I have been using physics to understand life-processes.


Statistical physics of Soft and Living Matter

Dr. Apratim Chatterji uses statistical physics to develop an understanding of the principles involved in the self-organization / self-assembly in typical soft matter systems (particles of micron-nano length scales). What are the resultant patterns formed due to interaction between macromolecules?

He has recently begun to use physics to understand self emergent shape and structure formation within the living cell, particularly the DNA. The bigger question, of course, is : How do physics processes (structure and dynamics) enable the cell to "live" ??

Dr. Chatterji uses computer simulations to explore and model the systems of interest.
