Dr. Jae-Won Choi is an Associate Professor in the Department of Mechanical Engineering at the University of Akron (UA).  Prior to joining UA in 2011, he spent one year for his Post Doctoral research in the W.M. Keck Center for 3D Innovation at the University of Texas at El Paso (UTEP) in 2007, sponsored by the Overseas Post Doctoral Fellowship from the Korea Research Foundations.  After his involvement with the W.M. Keck Center, he was promoted twice first to the rank of Research Specialist in 2008, and then to Research Assistant Professor in 2009.  Currently, he is serving as an editorial board member in several journals – Additive Manufacturing; International Journal of Precision Engineering and Manufacturing - Green Technology; and Korean Society of Manufacturing Processing Engineers.  His research interests include new processes and materials development in additive manufacturing; 3D printed smart structures and bio-structures; and low-cost 3D metal printing. He is a member of ASME, SME, and SPIE.

Research Accomplishments

Currently, he is intensively working on 3D printed tactile sensors for robotics, prosthetics, consumer products, etc.  He has secured several research grants for new AM processes/materials development.  He established eSens as a startup company for smart insoles, with AM technologies spun off from his lab.  He has one registered patent and several patent applications.  He has published more than 40 archival journal and conference papers.
