PhD Student

I’m a first year Ph.D student interested in space science and understanding/recreating Earth's history using geochemistry. I am particularly interested in the rise of free oxygen in Earth's atmosphere and understanding past global warming events (e.g., oceanic anoxic event 2, Paleocene-Eocene thermal maximum) to help calibrate models for the future based on what happened in the past. At ASU I am working on developing procedures to measure Re isotopes to determine their potential as a geochemical tracer.


I have a Master's of Science in geology from the University of Houston advised by Dr. Alan Brandon. My thesis research was on oceanic anoxic event 2 (~95 Ma) where I collected rhenium and platinum group element concentrations and osmium isotope data from sedimentary rocks deposited during the event.

When I'm not in the lab, I enjoy playing competitive video games. I currently play League of Legends (in-game name is Achimedes). In the past I was a semi-professional Halo player (Halo 2 and 3) and played more World of Warcraft than I like to admit. I’ve also been skateboarding for most of my life.
