Biography

Dr. Karakoc was born in 1959. He graduated from Anadolu University, the Department of Mechanical Engineering, in 1980. He received his M.Sc. degree in Mechanical Engineering from Yildiz Technical University of Istanbul, in 1982. He received his Ph.D. degree from Anadolu University of Eskisehir, in 1987. He started his full-time teaching at Anadolu University where he is now a Professor. He became an Assistant Professor and an Associate Professor, in 1988 and 1992, respectively. He received his full Professorship in 1997 from Anadolu University in Eskisehir. He has a wide range of research interests, some of his interest topics are “Sustainable Aviation, Aircraft Propulsion System, Insulation, Heating Ventilating and Air Conditioning (HVAC), Indoor Air Quality, Gas Turbines, Cogeneration Systems, Renewable Energy, Energy Economics, Fuels and Combustion”. He has taken part in numerous Industrial Projects on these topics as researcher, consultant and project manager. He served as a consultant for more than 30 corporations. He also started a contest on special insulation applications (tall buildings, hospitals, historical buildings, etc.) among the university students. He also served as an Editor-in Chief, and as a guest editor for international scientific journals. He published national and international papers over 300 and 40 books. He is an active member of Chamber of Mechanical Engineers and many sectorial associations, various international scientific organizations and societies.
