Dr. Leisawitz, an astrophysicist, is Chief of the Science Proposal Support Office in the Sciences and Exploration Directorate at NASA Goddard Space Flight Center. His primary research interests are star and planetary system formation, infrared astrophysics, wide-field spatio-spectral interferometry, and far-infrared space interferometry. He is NASA Center Study Scientist for the Far-IR Surveyor, Mission Scientist for the Wide-field Infrared Survey Explorer (WISE), and earlier served as Deputy Project Scientist for the Cosmic Background Explorer (COBE) under Project Scientist and mentor Dr. John Mather. Leisawitz is Principal Investigator for “Wide-field Imaging Interferometry,” a Co-Investigator on the “Balloon Experimental Twin Telescope for Infrared Interferometry (BETTII),” and member of a three-person External Advisory Panel for the “Far Infrared Space Interferometer Critical Assessment (FISICA),” a European Commission FP7 research program. In 2004-05, he served as Principal Investigator and science team lead for the Space Infrared Interferometric Telescope (SPIRIT) mission concept study. Leisawitz is current mentor to a NASA Postdoctoral Fellow and a NASA Space Technology Research Fellow, and former mentor to numerous students ranging from high school to early career. Dr. Leisawitz was twice tapped for detail assignments to the Astrophysics Division at NASA Headquarters, most recently to serve as Acting Assistant Director for Policy and Planning.
