Background

Dr Martay began her career in Sports Biomechanics. She used gait analysis to investigate how shoe type (very cushioned, very stiff) affected pressures experienced under the foot during running.
More recently, Dr Martay's research has been within Clinical Biomechanics. She used finite element modelling to investigate stresses within the knee and first metatarsophalangeal joint in the foot. In both projects, she created computer models to consider how variations in surgical procedures would affect joint mechanics post-surgery. These studies also involved validation studies.
Dr Martay is currently setting up a number of research studies within Clinical Biomechanics and Sports Biomechanics. Please get in touch if you are interested in joining her on research projects.
