Summary of Research

During my graduate studies, I will explore the reactive dynamics of liquid water at high pressures and temperatures generated by shock waves. My goal is to probe ionization, viscosity, and hydrogen bonding dynamics as the liquid compression approaches the superionic phase boundary.
The Dlott group established a tabletop flyer plate apparatus to produce shocks in samples by impact of a laser-driven flyer plate, launched with speeds of 0.7-4.5 km/s via laser ablation of a thin foil. By controlling the impact velocity of the flyer plate, we can shock liquids to precise regions in their phase diagrams with pressures up to 25 GPa. The pressure is determined from the Rankine-Hugoniot equations, while temperature can be measured from the relative intensities of Stokes and anti-Stokes scattering in Raman spectroscopy.
I will perform femtosecond IR spectroscopy on shocked liquid water to track the evolution of covalent stretching and bending transitions, which are sensitive to hydrogen bond interactions and proton concentration, respectively. Fluorescence anisotropy measurements reporting on rotational motion of dissolved chromophores will complement the spectral data and provide evidence of the dynamics in shocked water.
