About Me

Hello! I'm Jess Vriesema.

I am a computational physicist and planetary scientist specializing in numerical simulations of electrodynamics in the atmospheres of giant planets. As part of my current research, I am using computer simulations to understand how electrodynamics in Saturn's mid- to low-latitude thermosphere influences its temperature, structure and dynamics.

I am currently an associate lecturer for the Department of Physics + Astronomy at the University of Wisconsin–Eau Claire.

I did my doctoral work at the Lunar and Planetary Laboratory (Department of Planetary Sciences) at the University of Arizona.

I enjoy programming, playing board/card games, computer games, tabletop role-playing games, music (I play cello and guitar), hiking, and spending time with friends and family. My wife and I have two cats and a dog.

Reddit IAmA

On 18 September 2021, I participated in a Reddit IAmA so that people can ask me questions about planetary science or computational physics. It was a lot of fun!
