Sotirios Kokkalas is currently an Associate Professor in Structural Geology at the Petroleum Institute (PI), Khalifa University of Science and Technology, in Abu Dhabi. From the start of his academic career and for a decade (2003-2013) he lectured several courses and conducted research on the brittle deformation of the upper Aegean crust at the University of Patras (Greece). As a pure field geoscientist, he led several field trips on various tectonic settings in Europe and the Middle East. During 2006-2007 he was a visiting researcher at the Rock Fracture project in Stanford University, California (USA), where he participated in several field trips in Nevada and California. His main research interests are in the area of brittle and ductile faulting and fracturing in the upper crust with applications to the oil and gas industry, orogenic evolution of fold-and-thrust belts, strike-slip tectonics, magmatic intrusions, tectonic geomorphology and earthquake geology-paleoseismology.

During his academic career he has published numerous articles in peer reviewed journals and conference proceedings on various research subject areas such as, fracture and fault zone analysis, strain analysis of shear zones, orogenic deformation, active tectonics and paleoseismology. He also delivered several presentations and invited talks in international conferences and workshops and is the co-author of two books on Earthquake Geology and Geodynamics-Plate Tectonics for Greek university students. Furthermore, he serves as a reviewer for a great number of high-impact international journals in the area of Earth Sciences and Geodynamics. He is member of several professional organizations (GSA, AGU, EAGE etc.)
