Research Interests

The research activities in my group fall under the broad domain of inorganic and organometallic chemistry and catalysis. My group focuses on designing new pincer and N-heterocyclic carbene ligands and their transition metal complexes capable of the following type of reactivities:

  • Small molecule activation
  • C-H activation and functionalisation

Investigation of fundamental aspects of these activities and their mechanisms are carried out for the potential application in the development of renewable energy and sustainable chemical processes, including the following:

  • CO2 capture, functionalisation, and reduction
  • H2 production, storage, and transportation
  • Development of Liquid Organic Hydrogen Carriers (LOHCs)
  • Catalytic systems for hydrogenation/dehydrogenation reactions
  • Catalytic systems for C-C, C-N, and C-O bond-forming reactions
