Derek Yip-Hoi, PhD

He/His/Him, Professor


Dr. Yip-Hoi received his Ph.D. from the Department of Mechanical Engineering at the University of Michigan in 1997. His dissertation research focused on developing Computer-Aided Process Planning methods and software tools to support the automation of machining on Mill/Turn machining centers. Following his Ph.D. he worked for several years at the NSF Engineering Research Center for Reconfigurable Machining Systems at the University of Michigan. His work involved the supervision of sponsored R&D projects on Reconfigurable Manufacturing in collaboration with Ford, GM, and Chrysler. In 2003 he joined the faculty of the Mechanical Engineering Department at the University of British Columbia as junior chair of the NSERC-sponsored research program in Virtual Machining in collaboration with Pratt and Whitney, Canada. In 2007 he moved to the Department of Engineering Technology at Western Washington University as coordinator of the CAD/CAM option in the Manufacturing Engineering Technology program and following this director of the Manufacturing Engineering program.
