My research seeks to understand how molecular structure, dynamics, and fluctuations give rise to the remarkable properties of aqueous systems, from supercooled liquids to biomolecular condensates. By combining advanced X-ray scattering experiments at synchrotron and X-ray free-electron laser facilities with molecular simulations, my group investigates how water governs transport, self-assembly, and phase transitions across multiple length and time scales.

My group welcomes motivated students and postdoctoral researchers interested in chemical physics, soft matter, structural biology, and advanced X-ray methods.
