About


Bob Burkholder received his BSEE in 1984, his MSEE in 1985 and his PhD in 1989, all from The Ohio State University. He has since worked at the ElectroScience Laboratory where he is currently a Research Professor and served as Interim Director from 2016 to 2018. He is a Fellow of the IEEE and a Full Member of the International Union of Radio Science (URSI), Commission B. He is also a member of the American Geophysical Union and the Applied Computational Electromagnetics Society. Currently Dr. Burkholder is serving as Track Editor for IEEE Antennas and Propagation Letters.

Research Interests
Dr. Burkholder's research interests are in electromagnetic wave propagation and scattering theory, numerical modeling, and imaging applications in radar cross-section analysis, remote sensing, synthetic aperture radar imaging, near-field microwave imaging, ultra-wideband antenna design, and radio frequency identification (RFID). He has contributed extensively to the study of radar scattering and imaging of objects in the presence of a rough surface, ships on the ocean, and through-wall microwave imaging.
