Professional Background:

PhD in Physics, University of Pune

Postdoc:   Atomic Energy Center (CEA), Grenoble; US Naval Research Laboratory, Washington, DC.

Research Interests

My research goals are towards understandings the properties of molecules, nanocrystals and materials using density functional theory. Major efforts of my group are devoted towards the development of density functional based code and the self-interaction-free density functional approximations. The code development projects are UTEP-NRLMOL electronic structure code that allows density functional calculations upto 50000 basis functions; FLOSIC (Fermi-Lowdin Orbial Self Interaction Corrected (FLOSIC)) code for self-interaction free density functional calculations and DFTSW (Density functional theory in the South West) code for density functional calculations.
