Thomas González Roberts is a postdoctoral fellow in the Sam Nunn School of International Affairs at the Georgia Institute of Technology. Using tools from observational astronomy and computational astrodynamics, Roberts studies the behavior of Earth-orbiting satellites to understand how space actors—from superpowers to start-ups—engage with outer-space governance. His research interests include international coordination, sustainability, and security in space. Roberts’ work has been supported by the Harry S. Truman Scholarship Foundation, the National Science Foundation, and the Swiss State Secretariat for Education, Research, and Innovation. Roberts has earned numerous recognitions, including the Prize for Open Data from the Massachusetts Institute of Technology (MIT), the Geneva Centre for Security Policy’s Prize for Innovation in Global Security, and a placement on Forbes Magazine’s “30 Under 30 in Science” list. He holds a PhD and SM in aeronautics and astronautics from MIT, an SM in technology and policy from MIT, and a BA in astrophysical sciences from Princeton University.
