Gabriele B. Belle is an instructional associate professor in the Physics and Astronomy Department and the Deputy Mission Systems Engineer of the GMU/NASA Landolt Space Mission. Since joining Mason, Dr. Belle’s work has focused on science education and centered on course design and teaching. She developed the first online Astronomy and College Physics lab courses and was nominated several times for the Teaching Excellence Award. In 2024, she received the Faculty Member of the Year Award from the George Mason Alumni Association.

Dr. Belle supervises all college physics and astronomy lab courses. She also teaches physics in the Enlisted to Medical Degree Preparatory Program (EMDP2), in which military students are prepared to attend medical school. She served on the effective teaching committee and is also the co-founder and initiator of Mason Space Day. Recently, she joined the GM/NASA Landolt Space Mission Team as the Deputy Mission Systems Engineer. 

Before joining Mason, Dr. Belle worked in industry and was a visiting scholar in the Department of Astronautics at the United States Air Force Academy. Before coming to the United States, she was an assistant professor and technical director of a microelectronics research center at the University of Ulm in Germany. She was also a researcher at the Max Planck Institute for Solid State Research and the High Magnetic Field Laboratory (LNCMI) in Grenoble, France.

Dr. Belle's research encompasses compound semiconductor materials, nanotechnology, and GPS signals. As an experimental physicist, she investigated quantum well structures with laser spectroscopy in high magnetic fields, developed new semiconductor devices, and built satellites to explore the GPS signal above the GPS constellation, for which she received the Air Force Association’s Citation of Honor and the AIAA Special Recognition award.
