RESEARCH

Our research explores ultrafast electron dynamics in atoms, molecules, and biomolecular systems, with a focus on understanding and controlling electronic motion on attosecond to femtosecond timescales. Our program is articulated around several complementary topics in attosecond and strong-field science, unified by the development of first-principles theoretical and  computational methods for describing multi-electron dynamics in intense and ultrashort laser fields. Building on this methodological foundation, we are actively exploring how electronic coherence and density can be created and manipulated at the electronic timescale, and how charge migration and attochemistry may influence the earliest steps of chemical reactivity. We also study strong-field physics, where tunnel ionization, high-harmonic generation (HHG), and nonlinear light–matter interactions govern the nonperturbative regime. In this context, strong fields provide powerful routes to image molecular structure in real time through techniques such as high-harmonic spectroscopy (HHS) and light-induced electron diffraction (LIED). Finally, we model and interpret attosecond spectroscopies using XUV and X-ray pulses that offer direct, real-time access to electronic motion.
