Dr. Bruce A. Campbell Geophysicist Center for Earth and Planetary Studies National Air and Space Museum campbellb@si.edu

Bruce A. Campbell received his B.S. in Geophysics from Texas A&M University in 1986, and his Ph.D. in Geology and Geophysics from the University of Hawaii in 1991. He joined the staff of the Center for Earth and Planetary Studies in 1992. From 1996 to 1998, he was the Discipline Scientist for NASA's Planetary Instrument Definition and Development Program (PIDDP). He served as CEPS Chairman from 1998 until 2002.

Dr. Campbell's research interests focus on applications of radar remote sensing to the understanding of volcanism, impact cratering, weathering, and other surface processes on the terrestrial planets. This research has three complementary elements: theoretical studies of radar scattering, radar and field studies of locations on Earth that may be good analogs for other planets, and analysis of planetary remote sensing data. Much of this work over the past decade has emphasized the relationship of surface roughness to radar observations of volcanic surfaces, which remains a key element in interpreting data for Venus, the Moon, and Mars. Fieldwork in support of this includes the collection of a large database of high-resolution topographic profiles for lava flows in Hawaii. Recent projects have expanded this effort to include radar penetration and polarization signatures of Mars-like sand, dust, and ash deposits.

Dr. Campbell is also active in planetary missions and spacecraft development efforts. He has been involved in Discovery and New Frontiers mission proposals to send drop-probes into the atmosphere of Venus and to study the Moon with imaging radar, and is leading a team to develop an orbital imaging radar system for Mars. He is a team member for the SHARAD radar-sounding instrument on the Mars Reconnaissance Orbiter, which probes the upper km of the martian crust to identify geologic layering.
