Koray Tureyen

Senior Associate


Since joining WJE in 2002, A. Koray Tureyen has conducted investigations involving structural and materials-related problems of reinforced concrete, steel, masonry, and wood structures. His forensic engineering experience includes evaluation of damage caused by earthquake, explosion, wind, fire, corrosion, and construction accidents. Dr. Tureyen has also gained experience in exterior facade investigations and troubleshooting of water infiltration problems through roof and facade systems.

Before joining WJE, Dr. Tureyen was an instructor at Purdue University and taught materials engineering and senior design courses. Through his work as a graduate research assistant, he gained experience in bridge design with an emphasis on the use of fiber-reinforced polymer bars and large scale testing, instrumentation, and monitoring methods. Additionally, Dr. Tureyen has experience in earthquake damage evaluation and dynamic analysis of reinforced concrete structures as a result of his involvement in research following the 1999 Kocaeli and Duzce earthquakes in Turkey.
