Planetary interiors / high pressure physics

My name is Felipe González, and I am an Assistant Project Scientist at the Department of Earth and Planetary Science of the University of California, Berkeley. I am part of Burkhard Militzer's research team and my area of focus is the study of planetary interiors, specifically the physics of high-pressure and high-temperature matter. I obtained my PhD degree in physics from the Universidad de Chile in 2015, and in my research I use molecular dynamics and electronic structure calculations based on density functional theory (DFT) to understand matter at the atomic level. This approach allows me to determine equations of state for materials, even under conditions where experimental data is not available, which is crucial for constructing models of planetary structure and evolution. By advancing our understanding of planetary processes, both within our solar system and beyond, we can gain a deeper insight into the workings of the universe.
