I was born in Athens, Greece and I have resided in the U.S. since 1984. I received B.S. (1989) and M.S. (1991) degrees in Geophysics from Virginia Polytechnic Institute and State University, and a Ph.D. (1999) in Geological Sciences from The University of Texas at Austin. My professional experience includes exploration geophysics with Mobil Oil (1991 to 1995, offshore Gulf of Mexico), Jones Energy Ltd. (1996 to 1998, Texas Panhandle and Oklahoma) and the U.S. Department of the Interior (1999 to 2003, offshore Gulf of Mexico). In 2003 I joined The University of Kansas, Department of Geology, where I am currently a Professor.


My research interests are in applied geophysics, including near-surface geophysics, exploration geophysics and induced seismicity. My research has focused on ground-penetrating radar (GPR) imaging of fractures and monitoring flow and transport in fractured rocks, monitoring microbial processes in contaminated aquifers, geophysical imaging of polar ice sheets, application of geophysical methods to archaeology, GPR imaging of carbonate aquifers and reservoir analogues, and most recently seismic characterization of Mississippian and Arbuckle reservoirs in Kansas, seismic monitoring of CO2 storage, and monitoring of induced seismicity in the US midcontinent.
