Kallol received his B. Sc. and M. Sc. in chemistry from University of Calcutta, India. He received his Ph.D. in organic chemistry from the Saha Institute of Nuclear Physics (SINP), India in 2016. During his training with Prof. Sudipta Maiti's group at the Tata Institute of Fundamental Research (TIFR), India, he developed a method for quantifying and visualizing some of the key neurotransmitters including serotonin and dopamine.
Kallol joined the Lester lab as a postdoctoral fellow in October 2017. His work in the Lester lab has focused on unraveling the mechanisms underlying the rapid antidepressant effects of the drug ketamine. He is currently working on developing a family of fluorescent biosensors that can dynamically reveal the presence of ketamine and its metabolites at the sub-cellular level.
