Jennifer L. Yaek, P.E., CPST
Senior Managing Engineer
Vehicle Engineering
  • Detroit

Ms. Yaek has worked in the area of accident reconstruction and vehicle dynamics since 1995 and has provided accident reconstruction and vehicle dynamics analyses of all types of automobile accidents involving passenger vehicles, light and heavy-duty trucks, motorcycles, bicycles, pedestrians, buses, farm equipment, cranes, and industrial equipment. She has extensive experience in the reconstruction of complex accident situations including front, rear, and side high-speed collisions, low-speed collisions, pole/guard rail impacts, and post-collision fuel-fed fires. In addition, Ms. Yaek has extensive expertise in the investigation of vehicle rollover crashes including assessments of vehicle handling response, tire/component failure, rollover dynamics, and rollover stability.

Throughout her years of experience, she has conducted numerous physical demonstrations including high and low-speed full-scale crash tests, vehicle component testing, and vehicle handling response demonstrations. Ms. Yaek’s expertise also includes the analysis and use of computer programs and simulations and photogrammetry in the reconstruction of crashes and rollovers.

Ms. Yaek also has expertise in biomechanics of human injury, focusing in the areas of human injury tolerance, occupant kinematics, and rigid body dynamics associated with transportation related impacts, sports activities, heavy equipment, farm equipment, falls, and consumer products. Ms. Yaek is currently working on a Ph.D. in biomechanics of human injury, with her research focusing on child safety in side impacts. She is also currently a certified child passenger safety technician.

Prior to joining Exponent, Ms. Yaek consulted and testified as an expert witness on issues related to crash reconstruction, vehicle dynamics, vehicle handling response, and occupant kinematics with M.P. Holcomb Engineering for over 16 years. While at the University of Michigan, she was involved with the University of Michigan’s Transportation Research Institute’s (UMTRI) research in the areas of offset frontal impacts and lower extremity injuries.
