I am a Pluto climate scientist! I investigate how Pluto's climate and atmosphere are coupled to its surface ices and how they have varied with time over the age of the solar system. I use numerical modeling and observations from NASA's New Horizons spacecraft mission to do this work, alongside my advisor Dr. Leslie Young (SwRI). Additionally, I am broadly interested in the icy and ocean worlds of the outer solar system.
