Sunlight is a multi-faced source of energy since it impacts life through intricately woven networks of beneficial as well as harmful biophysical and biochemical transformations. This suggests that the effects of photoexcited electrons on downstream processes is subtle and mechanistic insights into such light-induced electronic processes in natural and artificial systems can result in novel ways to utilize sunlight for constructive purposes. Our primary interests lie in understanding light-induced vibronic phenomena, focusing specifically on photovoltaic applications and combating ultraviolet light induced aggregation of biomolecules, using first-principles based theories, mixed quantum-classical and quantum mechanical-molecular mechanics algorithms.

If you are a student (undergraduate, Int. Ph.D. or Ph.D.) of IISc and want to work with me, please email me.

A postdoc position is available in my group. If you are interested, please email me with your latest CV, names of 2 people who can write recommendation letters for you and a one-page summary of your Ph.D. thesis. I am also happy to help applicants apply for external fellowships such as National Postdoc Fellowship (NPDF) or Department of Biotechnology-RAships and so on.
