Our research program focuses on the dynamic visualization of ultrafast electronic processes of matter with light.  To this end, we  develop and utilize intense, ultrashort, laser pulses whose field-waveform is controlled with sub-cycle precision.  Under such fields, the interaction of laser and matter becomes extremely nonlinear and offers the possibility to devise new methodologies of probing the fundamental properties of electrons in a wide range of materials ranging from atoms to complex solids.  Understanding and controlling the microcosm at the level of electrons may turn essential in future photonic and electronic technologies whose building blocks size is gradually reducing from the mesoscopic to the atomic and molecular scales.
