Currently, we are interested in developing methods to synthesize and characterize model complexes to mimic intermediates involving in the Ribonucleotide reductase (RNR) and peroxynitrites in our research group. My research group also aims to develop strategic methods for the synthesis of high valent Ni(IV)-oxo species for the catalytic applications.

My research expertise ranges from photochemistry, electrochemistry, resonance Raman and X-ray Absorption spectroscopy of transition metal complexes in catalysis, and probing mechanisms of DNA-based asymmetric catalysis. My research work is primarily concerned with the spectroscopic characterization of short-lived reactive intermediates, which are directly implicated in the action of biological systems.

I played a central role in the development of Raman instrumentation and in training of under and postgraduate students, in my previous labs. I am also an expert in performing X-ray Absorption Spectroscopic experiments and the data analysis.
