Dr. Dimokratis Grigoriadis received his B.Sc. (1995) in Mechanical Engineering at UMIST (Manchester, UK) and his M.Sc. (1996) in Environmental and applied Fluid Dynamics from the Von Karman Institute for Fluid Dynamics (Belgium). In 1996 he joined the National Research Center  Isosurfaces of pressure fluctuations over an fixed bed 
“Demokritos” (Greece) initially working on environmental flows and later on computational and experimental nuclear thermal-hydraulics at the GRR-1 reactor. Received his PhD (2003) in Mechanical Engineering from the Aristotle University of Thessaloniki (Greece) on “Large Eddy simulations of turbulent flows in complicated geometries”. He joined the university of Cyprus in 2006 as member of the Ucy-CompSci group.
