Research Interests 
  • Theoretical chemical dynamics:  
  • Time-independent and time-dependent quantum dynamics of inelastic and reactive scattering: Integral and differential cross sections, state-selected and state-to-state energy resolved reaction probabilities, resonances, nonadiabatic coupling, spin- orbit coupling and geometric phase effects.  
  • Electronic spectroscopy of molecules and clusters: Potential energy surface, vibronic coupling, conical intersections, electronic nonadiabatic effects and transitions, photoabsorption, photoemission, photodissociation dynamics of molecules on coupled electronic states, photoelectron spectroscopy of negative ions and neutral molecules, Jahn-Teller and pseudo-Jahn-Teller and Renner-Teller effects. 
  • Electronic spectroscopy of boron and carbon cluster. Electronic control of molecular processes through conical intersections.
