PhD Candidate - dan.sullivan@asu.edu
I’m a Ph.D candidate interested in planetary science and understanding Earth's history using geochemistry. I am particularly interested in the rise of O2 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 test their potential as a geochemical tracer.
I have a M.Sc in Geology from the University of Houston advised by Dr. Alan Brandon. My thesis research focused on oceanic anoxic event 2 (OAE-2, ~95 Ma) where I collected rhenium and platinum group element abundance data 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 Lost Ark, Valorant, League of Legends, Escape From Tarkov, and Fortnite. In the past I was a semi-professional Halo player (Halo 2 and 3). I’ve also been skateboarding for most of my life.
