Dr Jennifer Martay

Lecturer in Engineering

Faculty:Faculty of Science & Technology

Department:Engineering and the Built Environment

Location: Chelmsford

Areas of Expertise: Biomechanics of human movement

Jennifer's background is in Biomechanics and Orthopaedics. She is interested in how the healthy person moves, and the potential mechanical factors which might causes diseases such as osteoarthritis.

Background

Jennifer's recent research has been within Clinical Biomechanics.  From 2008-2016, she largely focused on the knee joint, as well as the first metatarsophalangeal (big toe) joint in the foot.  In both projects, she investigated potential mechanical factors involved in osteoarthritis and the effects of variations of surgeries used to treat osteoarthritis.  These projects involved gait analysis, finite element analysis, and experiments which validated the finite element models.

She is also interested in Sports Biomechanics.  From 2007-2008, she used gait analysis to investigate how shoe type (very cushioned, very stiff) affects pressures experienced under the foot during running.  I am currently setting up new Sports Biomechanics projects.
