Dr. Athanassios A. Dimas was born in Athens (1963). His degrees include: Diploma in Naval Architecture and Mechanical Engineering (1985) from the National Technical University of Athens, and M.Sc. in Ocean Engineering (1988), M.Sc. in Mechanical Engineering (1988) and Ph.D. in Ocean Engineering (1991) all from the Massachusetts Institute of Technology.

He is currently the Chairman (2024-present and 2015-2020) of the Department of Civil Engineering at the University of Patras. Ηe is also a Professor in the same Department since 2013 and Director of the Hydraulic Engineering Laboratory since 2020. Previously, Dr. Dimas was employed as a post-doctoral research associate (1991-1994) in the Levich Institute at the City College of New York, as an assistant professor (1994-2001) in the Department of Mechanical Engineering at the University of Maryland and as an assistant professor (2002-2008) and an associate professor (2008-2013) in the Department of Civil Engineering at the University of Patras.

He is the author or co-author (Google Scholar profile) of 49 articles in refereed international journals and books, 120 articles in refereed international and national conference proceedings, about 20 conference abstracts, about 80 technical reports, as well as university notes for the courses he teaches at the University of Patras. He serves or served as the principal investigator of 35 funded research projects in the USA and Greece and a member of the research team in 13 more funded projects. He was awarded the Offshore Mechanics Prize (1991) by the Offshore Mechanics and Polar Engineering Council. He is the holder of an International Patent (U.S. Pat. No. 6512999, 2003), he has served as a referee of about 130 journal and proceedings articles, and he is a member of international and Greek scientific associations and panels.

His research interests are in the areas of Coastal Engineering, Harbour Works, Sediment Transport, Numerical and Theoretical Fluid Mechanics.
