I use density functional theory (DFT) and molecular dynamics (among other advanced first-principles methods) to study the behavior of light elements under extreme pressures and temperatures. In my work, I have identified several new phase transitions in dense fluids and solids with significant implications for how certain materials interact and evolve within planets. Specifically, I have worked extensively on the phase diagrams and thermodynamic stability of N2, CO2, MgSiO3, and MgO. I also work on developing new methods to predict crystalline phases and evaluate free energies of solids and liquids at finite-temperature.
