Research Focus

One of our research interests involves bio-mimetic synthetic structural and functional model study of metalloenzymes. In this context, we focus on understanding the role of microenvironment in enzymatic processes. Characterization of short-lived intermediates relevant to enzymatic processes is an important part of our research. With combined structural, spectroscopic, and kinetic studies we try to understand structure-function relationship for bio-mimetic processes.

We are also interested in exploring catalytic processes involving organic transformation, and small molecule activation like reduction of proton, carbon dioxide etc. Further, we pay our attention in understanding reaction mechanism and thermodynamic driving force for catalytic processes.
