I am a structural engineer and CEO of QUAKELOGIC. I earned my B.Sc. degree in Civil Engineering and M.Sc. degree in Engineering Seismology from the Middle East Technical University. My second M.Sc. degree in Structural Engineering is from the Bosporus (Bogazici) University in Turkey. My doctorate degree in Structural Engineering (major) and in Geotechnical Engineering (minor) is from the University of California, Davis. My postdoctoral studies were at the University of California, Berkeley. I authored and co-authored more than 120 peer-reviewed publications on various issues in structural engineering and engineering seismology. My research and publications are at www.quakelogic.net
