Astrophysicist & Developer 2017-Present
Giant Army
Maintained and developed code for the the Universe Sandbox astrophysics simulation game. Added new features related to orbital dynamics and life simulation.

Postdoctoral Fellow 2015-2017
Carnegie Department of Terrestrial Magnetism (DTM)
Conducted and published independent and collaborative theoretical research on the dynamics of exoplanets and debris disks, using my own computational models and tools developed in C, IDL, and Python.
