Previously I worked at Astranis, building, launching, and operating geostationary communication satellites. I hold a bachelor's in mechanical engineering from Cornell University. At Cornell, I was the Chief Spacecraft Engineer for a lunar CubeSat mission that demonstrated novel electric propulsion and navigation systems.
