Primary Interests
My present research and development activities are concentrated in the areas <strong>of</strong>
biomechanics, human walking, artificial limbs, orthoses, ambulation aids, and rehabilitation
engineering. This involves the design and development <strong>of</strong> modern technological systems
for persons with limb loss (prostheses) or existing limb disability (orthoses). The work is
applied but is conducted with a basic-research approach that seeks general understanding in
addition to achievement <strong>of</strong> tangible goals. The concept is that understanding will facilitate
advancements in designs and lead to new applications. The research and development
activities are carried on in the Dept. <strong>of</strong> Physical Medicine and Rehabilitation <strong>of</strong> the Feinberg
School <strong>of</strong> Medicine (Northwestern University) in conjunction with the Jesse Brown VA
Medical Center and with the Dept. <strong>of</strong> Biomedical Engineering (Evanston, IL). The main

Engineering Research Program, are physically located within the Rehabilitation Institute <strong>of</strong>
