Main research interests

My research expertise lies at the heart of ultrafast science, in particular ultrashort pulse laser science, generation, control, and characterization of ultrashort light pulses and their applications. This includes the development of new advanced light sources, spanning from the infrared (IR) down to the extreme ultraviolet (XUV) spectral range, which enable to investigate light‐matter interaction at the shortest possible time scale.

Key words: Ultrafast optics, laser development, attosecond science, strong-field physics, nonlinear optics, filamentation and biophotonics
