Timothy W. Simpson, Ph.D.

Professor of Engineering Design and Manufacturing

Timothy W. Simpson, Ph.D., is the Paul Morrow Professor of Engineering Design and Manufacturing Engineering at Pennsylvania State University. He holds a joint faculty appointment in Mechanical & Nuclear Engineering and Industrial & Manufacturing Engineering, in addition to affiliate appointments in Engineering Design, Information Sciences & Technology, and Architecture. He serves as co-director of the Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D), a manufacturing demonstration facility for additive manufacturing ( 

Dr. Simpson’s research and teaching interests include additive manufacturing and 3D printing, product family and product platform design, and multidisciplinary design optimization and trade space exploration. He has authored over 300 technical publications and edited 2 textbooks in these areas. He has received over $25M in funding to support his research from the National Science Foundation (NSF), Office of Naval Research (ONR), National Institute of Standards & Technology (NIST), and Defense Advanced Research Projects Agency (DARPA) among others, and he has collaborated on additive manufacturing and materials development projects with a variety of companies, including Bayer Material Science (now Covestro), Boeing, Lockheed Martin, LORD Corporation, Schlumberger, United Launch Alliance, and Volvo. With support from NIST, Dr. Simpson helped to develop the Roadmap for Additive Manufacturing Materials, and he serves on the Workforce and Education Outreach group of America Makes, the National Additive Manufacturing Innovation Institute. In 2015-2016, he served as the 3D Printing Fellow for Penn State University. He is a Fellow of ASME and an Associate Fellow in AIAA, and he received the 2014 ASME Ben C. Sparks Award and the 2011 ASEE Fred Merryfield Design Award. 

Dr. Simpson serves on ASME’s Design Engineering Division Executive Committee and ASME’s Design, Manufacturing, and Materials Segment Leadership Team. In 2014, he helped established ASME’s new 3D Printing Design Challenge (IAM3D), and in 2015, he helped launched ASME’s Additive Manufacturing & 3D Printing Conference (AM3D) and served as the Executive Chair of AM3D in 2015 and 2016. He served as a co-editor on the Special Issue on Design for Additive Manufacturing in ASME’s Journal of Mechanical Design, and he wrote one of the feature articles in the ASME Mechanical Engineering magazine’s special issue on additive manufacturing. He received his Ph.D. and M.S. degrees in Mechanical Engineering from Georgia Tech, and his B.S. in Mechanical Engineering from Cornell University.
