Biography
Dr. Jyotishman Dasgupta is an associate Professor at the Department of Chemical sciences . His work focuses on Coherent motions in form of specific delocalized nuclear motions usually arising from low-frequency modes have been frequently suspected to play a key role in photoactive systems. Consequently, tracing transient changes in atomic positions and elucidating reactive nuclear coordinates within a polyatomic system becomes imperative. Using combination of steady-state electronic spectroscopy along with pump-probe electronic and time-resolved Raman spectroscopy, His group aims to develop a unified mechanism of photoactive systems driven by collective motions in many of the potent artificial and natural molecular systems. In addition, we are also working towards unravelling the role of protein motions in chemically triggered enzyme action.
Research Interest
