Dr. Elmasry specializes in injury biomechanics, orthopedic biomechanics, human kinematics, human injury tolerance, vehicle occupant dynamics and kinematics, full human body modeling and simulation, footwear modeling and simulation, and finite element analysis (FEA). He has performed numerous evaluations to target improved joint function following injuries and surgical interventions utilizing physical experiments on human cadavers and state-of-the-art computational modeling.

Dr. Elmasry has extensive experience quantifying internal loads on soft tissue and skeletal structures with an emphasis on the lower extremities and lumbar spine. He received intensive training in conducting translational research to unravel biomechanical reasons associated with surgical failures due to joint instability and to identify biomechanical risk factors associated with injuries and negative clinical outcomes. Dr. Elmasry also has experience in conducting in vivo experiments to study human movement using high- speed cameras, force plates, and inertial measurement units (IMUs).

Prior to joining Exponent, Dr. Elmasry worked within teams of arthroplasty surgeons and biomechanical scientists at the Hospital for Special Surgery to leverage simulation of knee mechanics in healthy and diseased knees and following surgical intervention. He developed a multibody dynamics model of the knee to understand the interaction between ligament properties and implant design towards achieving knee stability following total knee replacement. He also used a six-degrees of freedom robot arm to conduct physical experiments on cadaveric knees to understand ligament engagement patterns under different loading conditions. During his Ph.D. in the Biomechanics Research lab at the University of Miami, he developed finite element models and conducted physical experiments using MTS machines to study the biomechanics of the lumbar spine following various fixation procedures and investigated failure modes of implant hardware. He further developed computer models to analyze various mechanisms that lead to intervertebral disc degeneration such as smoking and aging. Dr. Elmasry also worked in a gait lab where he conducted in vivo experiments to evaluate human movement and body performance.
