Present PositionAstrophysicist
Brief BioDr. Benford joined the Goddard Space Flight Center in Greenbelt, Maryland in 2001. Prior to this, he spent over two years in the Infrared Astrophysics Branch at Goddard, first as an NRC Research Associate, then as a Principle Physics Engineer for Raytheon/ITSS. He pursued research in far-infrared detector development as a Fellow of the GSRP program at Goddard from 1994-1998.He has pursued research in continuum detectors for ground-based submillimeter observations, near-Terahertz heterodyne receiver technology, submillimeter observations of star forming regions and ultraluminous galaxies, and cryogenic systems for space observatories. He has led and participated in several mission concept studies, including the SAFIR Vision Mission and, currently, the Destiny mission to characterize dark energy. His current primary research focus is in the development of ultrasensitive bolometers for far-infrared and submillimeter astronomy and supporting technologies.
