Ömer Aydan was born in 1955, and studied Mining Engineering at the İstanbul Technical University, Turkey (B.Sc., 1979), Rock Mechanics and Excavation Engineering at the University of Newcastle upon Tyne, UK (M.Sc., 1982), and finally received his Ph.D. in Geotechnical Engineering from Nagoya University, Japan in 1989. He worked at Nagoya University as a research associate (1987-1991), and at the Department of Marine Civil Engineering at Tokai University, first as Assistant Professor (1991-1993), then as Associate Professor (1993-2001), and finally as Professor (2001-2010). He then became Professor of the Institute of Oceanic Research and Development at Tokai University, and he moved to Department of Civil Engineering, the University of Ryukyus (Nishihara, Okinawa, Japan) as the professor of Material Science and he retired at the end of March, 2020 as Emeritus Professor. He has been an adjunct staff of the University of the Ryukyus Disaster Prevention Research Center for Island Regions since 2014 and served as the director of the Center until he retired. He established the natural disaster simulation facility at the center. Dr. Ömer Aydan has played an active role on numerous ISRM, JSCE, JGS, SRI and Rock Mech. National Group of Japan committees, and has organized several national and international symposia and conferences. He organized 2019 Rock Dynamics Summit in Okinawa in May 7-11, 2019 as the world top class conference in Rock Dynamics. He was also made Honorary Professor in Earth Science by Pamukkale University in 2008.
