Currently, our principal areas of research include the development of novel sources of attosecond pulse of light in the Extreme UltraViolet (EUV) wavelength regime with tailored temporal profile, the development of innovative methods to characterize such attosecond pulses, and the study of ultrafast dynamical processes in atoms, molecules, and complex system down to the attosecond timescale. We have developed new methods to track electrons motions in such systems, and we are now investigating the correlated electron dynamics in matter.
