Dr. Kefala earned a Bachelor of Science degree in Physics and a Master of Science degree in Medical Physics from the University of Patras in Greece. She continued her studies with a second Master of Engineering degree in Biomechanics, and a Ph.D. degree in Biomechanics from the University of Denver. Dr. Kefala has over eight years of experience in a dynamic research environment dedicated to advancing orthopaedic biomechanics, biomechanics laboratory testing, verification and validation techniques and three years of clinical experience as a medical physics assistant with solid background in engineering, science, and physics gained through research and coursework. She is skilled in performing data acquisition, analysis, and has published several studies to facilitate research into diverse topics. She is familiar with documentation requirements and bringing an organized and precision-minded approach to our Human Factors/Biomechanics group.
Dr. Kefala has completed research projects in accurately measuring joint kinematics during activities of daily living for informing diagnosis, helping design of treatments, and improving the design of prosthetic devices. The end-result of her Ph.D. research was to obtain healthy data from the hip and knee joint during different activities of daily living based on laboratory testing on human subjects with a dual fluoroscopy system that was synchronized with a motion capture system. The collected data was used as a reference for comparing the effectiveness of different prosthetic devices, and by accessing data that support computer models. The results, obtained from Dr. Kefala’s research work have been published in well established and high impact factor journals.
