Thomas D. Gillespie, Ph.D. Retires from Mechanical Simulation

In early 1996, Dr. Gillespie was one of the co-founders of Mechanical Simulation Corporation. Over his many years at the company, Dr. Gillespie has made valuable contributions too numerous to list. He is recognized around the world as a "thought leader" in the understanding of vehicle dynamics and associated simulation technologies.

Dr. Gillespie is a Research Professor Emeritus at the University of Michigan. He is retired from a 30-year career as a researcher at the University's Transportation Research Institute where his research focused on vehicle dynamics, road roughness, tire uniformity, tire-roadway interaction and simulation of these phenomena.

He is the author of the book, Fundamentals of Vehicle Dynamics, published by SAE International. While at the University, he taught courses in automotive engineering and Integrated Vehicle Systems Design. Additionally, he taught courses in vehicle dynamics at automotive manufacturers and suppliers. 

Dr. Gillespie's professional career has been primarily concerned with advanced engineering and research in the automotive and highway areas. From the beginning, his career spanned the breadth of these areas, ranging from applied research at the Pennsylvania State University in automatic controls and pavement friction test methods, to responsibilities as a Project Officer with the U.S. Army Corps of Engineers directing engineering and service tests on new military construction equipment. While working at Ford Motor Company, he served as a group leader in development testing of new heavy truck products, as well as development of analytical methods and computer programs for predicting truck braking, handling, and ride performance. His expertise in the area of road roughness and vehicle dynamic interactions led to consultation with the World Bank directing an international experiment in roughness measurement. This led to the development of a worldwide standard - the International Roughness Index - by Dr. Gillespie and others (including Dr. Michael Sayers, another co-founder of Mechanical Simulation).

In 1987-88, he served on the White House staff as a Senior Policy Analyst in the Office of Science and Technology Policy. He later served as a consultant to the White House, chairing the Interagency Task Force to develop a National Action Plan on Advanced Superconductivity Research and Development.

Please join us in wishing Tom a long, safe, healthy, and active retirement.
