Jessica L. Isaacs, Ph.D.
Associate
Biomechanics
  • Philadelphia

Dr. Isaacs has a multidisciplinary background conducting research in bioengineering, materials science and engineering, and mechanical engineering. At Exponent, she focuses on issues involving human injury biomechanics and evaluates kinematics and mechanisms of injury. Her work includes evaluation of injuries occurring in vehicular, pedestrian, occupational, recreational, and fall-related accidents, as well as injuries associated with the use of consumer products.

Dr. Isaacs’ doctoral research at Drexel University focused on spine biomechanics, the effects of degeneration and age on the intervertebral disc, and injectable hydrogels. She completed a Fulbright Fellowship at Tel Aviv University in Israel. During her time in Israel, she focused on predictive multi-parametric computational biomechanical models for diagnosis, management, and repair of lumbar spine pathology, as well as characterizing fiber reinforced bio-composite materials. 

Prior to joining Exponent, Dr. Isaacs was a visiting assistant professor in the mechanical engineering department at Widener University. During her tenure she taught a variety of undergraduate courses, acted as faculty advisor for the Society of Automotive Engineers, and participated in various STEM outreach events.
