Greg Ushomirsky is chief scientist at STR (formerly Systems & Technology Research), a defense technology firm, where he leads advanced research in radar, space surveillance, and national security applications. At MIT Lincoln Laboratory, where he spent much of his career, he held technical leadership roles in radar tracking, satellite imaging and identification, and space payload development; among other contributions, he conceived and led development of a multistatic radar system enabling 3D imaging and precise metric tracking of satellites, and served as an assistant group leader overseeing advanced sensor concepts for space surveillance and control. He began his career as a Lee A. DuBridge Prize Postdoctoral Fellow at Caltech, where he conducted independent research on thermonuclear instabilities on accreting neutron stars and the fluid dynamics of their atmospheres and cores. He received his Ph.D. in astrophysics from UC Berkeley, where he was a Hertz Fellow.
