My current research interests include the development of efficient organic synthetic methodologies based on transition metal-catalysis, their application to asymmetric organic synthesis, and synthesis of organometallic complexes in search of new reactivity.

1. Transition metal-catalyzed organic synthesis
   1. Cu, Zn-catalyzed reductions
   2. Cu, Pd-catalyzed coupling reactions
2. Catalytic asymmetric synthesis; development of new chiral ligands
3. Synthesis of organometallic complexes and studies on their reactivity
