Jeff Hoffman began at HSS as a research engineer in the biomechanics department in March 2019. As a research engineer, he leads testing exploring the biomechanics of the foot and ankle using a validated 6-degree of freedom robotic gait simulator. Currently, he is examining the effect of surgical interventions on a validated model of progressive collapsing foot deformity during walking. Additionally, he is working with clinical staff to evaluate the effect of tibial implant design on early stage micromotion after total ankle arthroplasty. Previously, Jeff has worked on biomechanical projects aimed at addressing common pathologies of the foot and ankle, such as Jones’ fracture and Lisfranc injuries.
In addition to foot and ankle work, Jeff is involved in uniaxial mechanical testing for various projects around the lab.
Prior to HSS, Jeff received his M.S. in Biomedical Engineering from Drexel University in 2018. During his time at Drexel, he worked in collaboration with the motion laboratory at Shriners Hospital for Children in Philadelphia to evaluate the changes in pediatric spinal motion with age in healthy and scoliotic patients. Jeff received a BS in Biomedical Engineering from the University of Delaware in 2016. During his time at UD, Jeff worked as an undergraduate research assistant to evaluate the effect of functional electrical stimulation during gait in pediatric patients with cerebral palsy.
