Research Interests

My research projects focus on the development and use of advanced laser-based systems for the coherent control of strongly correlated quantum phenomena by optical means. I have extensive experience in nonlinear optics, ultrafast multi-terawatt laser systems, generation and coherent detection of phase-stable, extremely intense terahertz and mid-infrared pulses. Moreover my expertise extends to complementary techniques for steady-state characterization of solids including Fourier transform IR spectroscopy, Raman spectroscopy, X-ray scattering. The results of my projects are of interest to researchers working particularly in the fields of quantum phase transitions, ultrafast phenomena, and nonlinear light-matter interactions offering new prospects for future technological applications.
