Bruce Campbell received a Ph.D. in 1991 from the University of Hawaii for his radar polarization studies of volcanic and impact-cratered terrains on the Moon, Earth, and Venus. He took a position at the Smithsonian Institution's Center for Earth and Planetary Studies in 1992. His research interests include comparative studies of planetary terrains using imaging radar data; high-resolution topographic studies of planetary analogue surfaces; and analysis of scattering, shadowing and emission relationships in radar and visible/IR remote sensing. Dr Campbell also managed the NASA Planetary Instrument Definition and Development Program, which develops advanced spacecraft instruments and new remote sensing technologies, from 1994 to 1996. He became Department Chairman of the Center for Earth and Planetary Studies in 1998.
