Mother Nature has designed a wide range of metalloenzymes to perform chemical reactions selectively and efficiently. The study of structural and functional aspects of metalloenzymes by mimicking their active-site structures with small synthetic model compounds is an exciting area of research. Our research group focuses on developing advanced catalysts based on transition metal ions for various catalytic reactions of biological and technological importance. Our studies aim to understand the reaction mechanism of the catalytic processes at the molecular level. The mechanistic investigations are followed using combined spectroscopy, electrochemistry, kinetics, and computational studies. The group is currently involved in the followings research areas:
(1) Synthetic Bioinorganic Model Chemistry
(2) Bioinspired Redox Catalysis Using Transition Metal Complexes
(3) Water Splitting Chemistry Towards Artificial Photosynthesis.
