Sambit Das is a postdoctoral research fellow in the Department of Mechanical Engineering at University of Michigan, Ann Arbor, USA. His research interests are electronic structure studies on defects in materials and computational method development for large scale electronic structure calculations. Sambit is one of the principal developers of the open source DFT-FE code -- a massively parallel adaptive finite-element code for first principles based materials modelling using Kohn-Sham density functional theory. Sambit received his Ph.D. in Mechanical Engineering in 2019 from University of Michigan, Ann Arbor, USA, and B.Tech. and M.Tech. in Mechanical Engineering in 2013 from Indian Institute of Technology, Kharagpur, India.
