Received B.S. degree (with highest distinction) from the University of Kansas, Lawrence, in 1986 and the M.S. and Ph.D. degrees from the University of Illinois, Urbana-Champaign, in 1989 and 1991, respectively, all in electrical and computer engineering.
From 1991 to 2003, was with the Radar Science and Engineering Section, Jet Propulsion Laboratory (JPL), California Institute of Technology, Pasadena
From 2003 to 2011, was at the University of Michigan, Electrical Engineering and Computer Science department.
Started at USC in January 2012, as Professor of EE-Electrophysics.
Introduced innovative approaches and algorithms for quantitative interpretation of multichannel radar imagery based on analytical inverse scattering techniques applied to complex and random media.
Have developed quantitative approaches for multisensor data fusion by combining radar and optical remote sensing data for nonlinear estimation of vegetation and surface parameters. Have led the development of new radar instrument and measurement technologies for subsurface and subcanopy characterization.
Have been a a Systems Engineer for the Cassini Radar and the Science Chair of the JPL Team X (Advanced Mission Studies Team).
My research group is engaged in a number of research projects related to applied electromagnetics and wave physics, including the development of advanced radar systems for subsurface characterization, radar inversion and classification techniques for large-scale environmental applications, mixed-mode high resolution medical imaging and therapy techniques, and smart sensor webs for remote sensing data collection and validation. Have been the Principal and Coinvestigator on numerous research projects, authored or coauthored over 200 peer-reviewed publications.
