Research interests

  • Bioinspired catalysis: Epoxidation of alkenes, C-H bond hydroxylation, and Dioxygen reduction reactions
  • Inorganic reaction mechanism and spectroscopy: Trapping of Metal –Oxo, -peroxo, -superoxo, and –nitrenes as possible reactive intermediates in transition-metal mediated catalytic oxidation reactions.
  • Coordination and Organometallic Chemistry
