Tommy Grav

Tommy Grav (born November 8, 1973) is a Norwegian astrophysicist who worked on understanding the physical and dynamical properties of the irregular satellites of various planets (Saturn, Uranus, and Neptune) and their implication for early planetary formation and migration.

Grav studied at the University of Oslo, where he also received his doctorate in 2004. He then worked at the Institute for Astronomy, University of Hawaii, as a Junior Scientist on the Pan-STARRS project. He worked with the Moving Object Processing System (MOPS) team, developing and testing the software needed to discover and track new and known asteroids in the Pan-STARRS survey data.

In 2008, Grav joined Johns Hopkins University as an Associate Research Scientist.

He did his doctoral thesis research at the Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts, as a Smithsonian Pre-doctoral Fellow.

Grav was a member of three different astronomer teams (Gladman et al., Holman et al., and Kavelaars et al.).
