Biosketch

Kousik Samanta is the principal investigator in the Quantum Chemistry Laboratory at the School of Basic sciences at IIT Bhubaneswar. He received his undergraduate degree (B.Sc. with Honours in Chemistry) from R.K. Mission Vidyamandira, affiliated to University of Kolkata in 2001 and masters (M.Sc.) with a specialization in Physical Chemistry from Indian Institute of Technology Bombay in 2003. The masters project under the supervision of Prof. Manoj K. Mishra was instrumental in deciding his future career. He received his Ph.D. degree in Chemistry from Texas A&M University, College Station in 2009. During his doctoral research, he developed multiconfigurational self-consistent field method based on a complex-scaled Hamiltonian (CMCSCF) to study metastable states under the supervision of Prof. Danny L. Yeager. After the Ph.D., he was fortunate to work with Prof. David R. Yarkony (Johns Hopkins University) to study non-adiabatic effects and conical intersections until 2010. Later, he was drawn to another electronic structure theorist Prof. Gustavo E. Scuseria of Rice University. Until 2012, he worked in Gus’s wonderful team to develop projected quasi-particle method (a highly sophisticated method that gives rise to wavefunctions of multireference character at the cost similar to a mean-field method). Then he moved to University of Pennsylvania to work with Prof. Joseph E. Subotnik to develop semi-classical methods for the simulation of dynamics. He returned to India in the summer of 2014 and joined IIT Bhubaneswar as an assistant professor in the Chemistry Discipline at the School of Basic Sciences.
