He has done accelerator-based experiments at most of the world’s leading laboratories, including DESY, CERN, Fermilab, and SLAC. As a post-doc and faculty member at Columbia, he worked on the ZEUS experiment at the HERA electron-proton collider. Since 1996, he has been very active in the Fermi Gamma-ray Space Telescope (née GLAST). He was the Project Scientist for the Fermi mission from 2003 through most of the first year of science operations, and in 2009 he moved from NASA Goddard Space Flight Center to UCSC.
