Lile Squires is an Assistant Professor of Manufacturing Engineering. He holds a PhD in Mechanical Engineering from Washington State University, where he specialized in metal additive manufacturing and wire-arc directed energy deposition.
His professional experience from 2008 to 2021 was in future production systems, new product introduction, product development, and production welding. During this time, he held roles as a Manufacturing Engineer at Boeing, Process Engineer at ATC Manufacturing, and Operations Manager and Fabricator at STS Turbo. His work contributed to the development of the 777X, 787, and NMA airplane programs, as well as advancements in thermoplastic composite stamp forming and forced induction turbo systems.
He earned both his BS and MS in Manufacturing Engineering Technology from Brigham Young University, focusing on systems and conducting research in solid-state friction bit joining.
