Brief Resume


Born in Kayseri-Turkey in 1973.. Between 2005 and 2007, he worked as a postdoc at the Department of Mathematics of University College London, UK. From 2007 to 2008, he served as a research associate at the Department of Aerospace Engineering Sciences of University of Colorado at Boulder, USA. In 2009, he was appointed as an assistant professor of Astronautical Engineering Department at Istanbul Technical University and he is currently carrying out this position. His current research interests cover advanced numerical methods, high-performance computing, flow instabilities, non-Newtonian flows, computational aerodynamics, multi-phase flows and bio-fluids.
