Summary

I am a Post Doctoral Research Associate in the group of Christian Holm at ICP. I am a theoretical physical chemist by training. My research interests include condensed phase dynamical processes in chemical physics, physical chemistry of polymer nanoparticle mixture, nanoparticle suspensions and biology inspired physics.

I did my PhD from the Department of Inorganic and Physical Chemistry, Indian Institute of Science under the supervision of Prof. K . L. Sebastian. I was a Post Doctoral Research Associate in the group of Prof. Kenneth S Schweizer at the Department of Materials Science and Engineering, University of Illinois at Urbana Champaign from February 2009 to January 2011.

Currently I am using molecular dynamics simulation and analytics to analyze the tracer diffusion inside a cylindrical nano channel grafted with polymeric chains from inside. The model under study has essential features of the central plug of nuclear pore complex.
