In our group, we focus on both experimental and theoretical studies at the interface of ultrafast nonlinear optics, attosecond science, quantum optics and nanoscience. More specifically, our work involves generation, measurement and control of the interaction of light and matter in atoms, molecules and nanosystems in space and time at extremely short, up to attoseconds (~attosecond=10^(-18)sec) time scale. Our interests range from fundamental physical phenomena associated with these processes to practical applications.
