Current research interests:
Ultrafast Quantum Dynamics of Atoms and Molecules:
I am interested in dynamics of atomic and simple molecular systems exposed to shaped intense fs/as light pulses. The basic objective of my research has been two-fold: (i) to develop an understanding of the emerging phenomena when atomic/molecular systems interact with ultrafast light pulses, and (ii) to explore new quantum control scenarios of the fundamental photo-processes such as ionization, dissociation, electron localization etc.
Stochastic nonlinear dynamics:
I want to investigate phenomenon akin to Stochastic Resonance (SR) where an addition of noise (or disorder) into a nonlinear system can indeed improve its response.
