John Ekaterinaris

Professor Ekaterinaris obtained his B.Sc. in Electrical and Mechanical Engineering from Aristotle University of Thessaloniki, in 1977. He received his M.Sc. in Mechanical Engineering in 1983, and his Ph.D. in Aerospace Engineering in 1987, both at the Georgia Institute of Technology. 

Professor Ekaterinaris has worked at NASA-Ames Research Center, Moffett Field CA — through the Navy/NASA joint Institute of Aeronautics — since 1987, and at the same time was faculty at the Naval Postgraduate School at Monterey.

He spent more than a year (1995-1997) at RISOE, Denmark's national laboratory (wind energy department), and then worked at Nielsen Engineering and Research (1997-2000). He returned to Greece, and he became professor at the school of Mechanical and Aerospace Engineering of the University of Patras.

His interests are methodology development in computational mechanics, including aerodynamics, magnetogasdynamics, flow transition, turbulence research, flow structure interaction in aeronautics and biomechanics and multi-scale phenomena. 

He has been member of AIAA (where he served as a member of technical committees), and an AIAA associate fellow since 1995. He is editor-in-chief of the Journal Aerospace Science and
Technology, and associate editor of the Journal Progress in Aerospace Science.

  • Ph.D. - Doctor of Philosophy in Aerospace Engineering, Georgia Institute of Technology-Main Campus
  • M.S. - Master of Science in Mechanical Engineering, Georgia Institute of Technology-Main Campus
