R. Matthew Brach, Ph.D., P.E.

Senior Managing Consultant

Manager of Illinois Operations

Dr. Matthew Brach brings over 20 years of automotive engineering experience including time in automotive manufacturing and in the consulting business. His areas of technical specialization include vehicle impact analysis, vehicle dynamics, automotive accident reconstruction, railway grade crossing crashes, and automotive safety. Dr. Brach has analyzed and reconstructed crashes that involved commercial vehicles, light vehicles, motorcycles, bicycles, pedestrians, off-road vehicles, locomotives and trains, as well as crashes involving a horse and buggy. These projects have also involved aspects of human factors, visibility issues, and mechanical design issues. His approach to vehicle crash analysis and reconstruction involves the latest software and simulation tools, as well as data acquisition tools.

Over the course of his career, Dr. Brach has authored numerous technical papers and articles, primarily in the field of crash reconstruction, but also including topics in the area of vibrations and acoustics. He was a co-instructor of the SAE Accident Reconstruction Methods Continuing Education Seminar for more than a decade. He is co-author of the book, Vehicle Accident Analysis and Reconstruction Methods, which is now in its second edition.

His experience prior to joining ESi includes engineering positions with Ford Motor Company and IIT Research Institute. He was also an adjunct professor of Mechanical Engineering at Lawrence Technological University.

He earned a Ph.D. in Mechanical Engineering from Michigan State University, an M.S. in Mechanical Engineering from the University of Illinois at Chicago, and a B.S. in Electrical Engineering from the University of Notre Dame. He is also the Manager of Illinois Operations for the ESi office in Aurora, Illinois.
