Sarah K. Easley, Ph.D., P.E.
Senior Engineer

Professional Profile

Dr. Sarah Easley is a Senior Engineer in Exponent’s Mechanical Engineering practice.
Dr. Easley specializes in solid mechanics, biomechanics, finite element analysis (FEA), and
mechanics of materials. Dr. Easley has extensive experience performing numerical analyses of
consumer electronics and medical devices. Her doctoral research at the University of
California, Berkeley focused on using microstructural imaging, experimental testing, and
computational analysis to understand the relationship between bone structure and bone strength
and the effects of disease and treatment on that relationship. Her earlier graduate work focused
on design and analysis of orthopaedic biomedical devices.
Prior to joining Exponent, Dr. Easley worked as an intern at DePuy Orthopaedics in the
Research and Development department. During her time there, she developed FEA-based
surgical-planning software tools for predicting kinematic performance of knee replacement
devices. She also has experience using shop equipment such as lathes and milling machines,
and participated in the design and fabrication of a robot for the national F.I.R.S.T. competition.
