My research aims at elucidating the mechanism of the copper containing enzymes Nitrite Reductase (NIR) and Nitrous Oxide Reductase (N₂OR), which catalyze the second and last step respectively, of the bacterial denitrification cycle. I am also studying the mechanism of cofactor biogenesis of topaquinone in mononuclear copper Amine Oxidase, and related model complexes.

I use several spectroscopic techniques such as Absorption, CD, MCD, resonance Raman, EPR and DFT calculations to understand the ground state wave function of these enzymes and related model complexes. I also perform parallel kinetic studies using stopped flow kinetics and rapid freeze quench techniques to elucidate the steps involved in the enzymatic turnover.
