Reşat Ulusay, born in 1952 in İzmir (Turkey), obtained BSc and MSc degrees on engineering geology from the Geological Engineering Department at Hacettepe University (HU) in 1975 and PhD degree from the Middle East Technical University (METU) in 1991, Ankara, Turkey, respectively.
His main research activities are concentrated on engineering geology, rock mechanics and soil mechanics; particularly on slope stability, rock mass characterization and classification, laboratory and in-situ geomechanical testing, geo-engineering at historical sites, earthquake-induced ground deformations, attenuation relationships and swelling.
Between 1975 and 1996, he worked at the Mineral Research and Exploration Institute (MTA) of Turkey and was trained on mining geotechnology by Golder and Hoek Associates in UK and assigned to establish the Rock and Soil Mechanics Division and Laboratories under the auspices of the UN. During this period, he was involved in a number of geotechnical projects as engineer/manager, Division Chief and Deputy Head of the Department. He became Associate Professor in 1994. Between December 1995 and 1 September 2019 he worked at the Applied Geology Division of the Geological Engineering Department at HU. He became full Professor in 2000. He has also been a part-time instructor in METU between 1992 and 2015. He supervised a number of MSc and PhD theses and retired on 1 September 2019.
He is the author and/or co-author of about 300 papers, four technical books (Turkish) on rock mechanics and geotechnics, two dictionaries on geo-engineering and rock mechanics, and the Co-editor and Editor of the ISRM Blue Book and Orange Book, respectively. He is the Editor-in-Chief of “Bulletin of Engineering Geology & the Environment” and the Ex-Officio Executive Committee Member of the International Association of Engineering Geology (IAEG) since January 2019.
He is the President of ISRM Commission on Testing Methods, member of ISRM Design Methodology Commission and ISRM Fellow since 2006, 2008 and 2015, respectively. He presented 8th ISRM Online Lecture. “2016 Hans Cloos Medal” of IAEG was conferred to Prof. Ulusay for his contribution to the development of engineering geology. He also acted as President of the Turkish Society of Engineering Geology and member of Turkish Earthquake Advisory Board.
