+ The goal of this new project is to determine to what degree too large a socket impacts the health and
quality of life of individuals with transtibial amputation using prosthetic limbs. The clinical relevance of
this research is to promote quantitative standards for socket replacement based on prosthetic fit rather
than duration of prosthesis use, as is current practice.

monitoring of limb volume for maintenance of limb volume/mass"(October, 2010)
The goal of this research is to create a multi-channel bioimpedance analysis system to monitor regional
fluid volume changes in residual limbs of soldiers, veterans, and civilians using prosthetic limbs. Clinical
research studies are conducted to evaluate state-of-the-art volume management devices, and to evaluate
the use of volume feedback control towards enhancing limb fluid volume stability and patient satisfaction.
