Owen is Vice President of YA Engineering Services (YAES). His work focuses on solving complex problems on a wide range of structure types from high-rise buildings to bridges, historic monuments and sculptures. He has specialized expertise in assessing the effects of earthquakes on existing structures including having conducted damage assessments after a number of domestic and overseas earthquakes. Owen’s work includes field investigations of damaged and collapsed structures and performing evaluations and analyses using a wide range of modeling techniques. Owen joined YAES in 2019. Prior to joining YAES he spent eleven years at Wiss, Janney, Elstner Associates, Inc. (WJE) in Emeryville, California. Prior to joining WJE, Owen attended Hong Kong Polytechnic University where he was a post-doctoral fellow. In addition to his many years of civil and structural forensic engineering experience, he has extensive research experience in concrete and masonry structures, including rehabilitation using fiber reinforced polymer (FRP) materials.
