Instructor: Patrick Stickler, Ph.D., UW Affiliate Instructor and Boeing Associate Technical Fellow

Dr. Patrick B. Stickler received a BS degree in Industrial Engineering from Pennsylvania State University. He has Master of Science degrees from Lehigh University and the University of Washington in Manufacturing Systems and Mechanical Engineering, respectively. His Ph.D. is in Mechanical Engineering from the University of Washington. His doctoral research work was on mechanical behavior and failure mechanisms of composite T-Joint with transverse stitching. Dr. Stickler has worked at Boeing for the past 15 years in manufacturing, design, and research engineering. He is currently on assignment with the 787 Program in Everett, Washington in Technology Integration.
