TSOKAS, Grigorios

Professor of Geology, Director of the Laboratory of Exploration Geophysics, Aristotle University of Thessaloniki;

Born in Athens, he holds a diploma in Physics (1979, Aristotle University of Thessaloniki -AUTH), a M.Sc. in Exploration Geophysics (1980, Leeds University, U.K.) and a Doctorate in Geophysics (1985, AUTH). He has been trained as a resident geophysical programmer by the Western Geophysical Company, Hounslow-London (1988), on behalf of the Greek Public Petroleum Company (currently Hellenic Petroleum). He was visiting researcher at York University, U.K., (1990) and visiting professor at the Colorado School of Mines, U.S.A., (1994). Prof.  Grigorios N.  Tsokas is currently Director of the Laboratory of Exploration Geophysics of the Aristotle University of Thessaloniki (AUTH) and Vice President of the International Society for Archaeological Prospection (ISAP). His research interests are: Potential Fields theory and practice in Exploration Geophysics, development of Archaeological Prospection data acquisition, processing and interpretation techniques and Complex Attributes analysis of the geophysical signals. He has conducted more than 300 surveys in archaeological sites in Greece and abroad. He is author of more than 180 papers (about 120 in peer-reviewed ISI journals) and awarded several international distinctions (best paper of the year 1997 in electrical methods, invited papers, invited speaker, 3 best paper awards in worldwide conferences, editor of journals and member of international committees). His contribution to archaeological prospection is internationally recognised for his studies in inversion filtering of magnetic data from archeological sites, the adaptation of the Electrical Resistivity Tomography (ERT) for investigating in urban environment, the seismic refraction and ERT schemes developed for imaging the interior of tumuli, the introduction of the complex attributes to assist the interpretation of magnetic data and the introduction of functions for detecting the edges of the buried ancient remains.
