George Tsoflias received a B.S. (1989) and M.S. (1991) in geophysics from Virginia Polytechnic Institute and State University, and a Ph.D. (1999) in geological sciences from The University of Texas at Austin. He was employed as a geophysicist for Mobil Oil from 1991 to 1995 and for the U.S. Department of the Interior from 1999 to 2003. Since 2003 he has been an assistant professor at The University of Kansas, Department of Geology. Tsoflias’ research interests include the study of ground-penetrating radar and seismic methods for characterization of near-surface anisotropy and its effect on the fluid-flow properties of geologic formations. His current research involves the study of GPR signal polarization properties for the characterization of natural fractures.
