Research Interests

Investigation of the interaction of molecules with weak and strong electromagnetic fields produced by various light sources. Recent research interests are in the areas of non-linear physics, quantum control and time resolved studies of molecules with emphasis on long and short wavelength radiation, ultrafast time scales and strong laser fields. The current research involves the use of intense femtosecond and HHG table-top lasers and free electron lasers (FEL) in the vuv and x-ray regimes to probe physical and chemical processes that happen on ultrafast time scales. Planned investigation with trains of attosecond pulses and x-ray FEL pulses are underway.
