Summary of Research

I use supercomputers to study tiny things at enormous pressures and temperatures. More precisely, I utilize ab initio simulation methods to study molecular properties at extreme conditions, with a focus on theoretical vibrational spectroscopy. I'm currently computing Raman and IR spectra of water and ice at planetary core conditions. Understanding the physics of water at these conditions informs our understanding of the deep water and deep carbon cycles, with application to climate and planetary science. More generally, I am interested in understanding hydrogen bonding at extreme conditions in relation to geoscience, materials engineering, and fundamental physics. I also maintain interest in extreme conditions materials research at large, particularly in the use of pressure as a thermodynamic dial in the tuning of desirable mechanical and energetic properties.
