Prof. Nikolay Bonev is a faculty member of the Department of the Geology, Paleontology and Fossil Fuels at the Sofia University “St. Kliment Ohridski” in Bulgaria. He graduated as a geologist-geochemist in the latter university, with a MSc thesis on igneous petrology. He obtained in the same university a PhD in geotectonics and a DSc in geotectonics and regional geology. He was a post-graduate research fellow in the University of Montpellier 2 (France) in 1993, post-doctoral research fellow in the University of Lausanne (Switzerland) between 2002 and 2005, and a Fulbright senior research scholar in the Miami University of Ohio (USA) in 2008-2009. Prof. Nikolay Bonev is deeply involved in the research of tectonics, regional geology and geodynamics of the northern Aegean region on the territories of Bulgaria, Greece and Turkey and participated in international projects, including three SCOPES (Switzerland-eastern Europe) and three Swiss National Science Foundation projects. He has multidisciplinary research interests in the field of structural control on extension-related epithermal gold deposits and mineralizations, whole-rock and isotope geochemistry, petrology, tectonics, regional geology and geodynamics. On a national level, Prof. Nikolay Bonev has coordinated four national research projects, financed by the Ministry of Education and Science, one related to extensional tectonics of the eastern Rhodope Massif in Bulgaria, another on the geochronology of the part of the Saka
