Associate Dean for Research
Georgia State University
My research to date brings together the disciplines of Physical Therapy and Biomedical Engineering. My
expertise in these two disciplines has helped me focus my research endeavors towards improving
function, mobility, health and wellbeing in individuals with various neurological disorders. To that extent I
have developed new technologies using wearable sensors and/or used existing technologies to study and
understand human movement. I have also been instrumental in developing and testing a prototype robot driven gait orthosis that allows patients with SCI to perform stepping in a supine position. I have written
computer programs to collect and analyze data from biological signals such as electromyograms, evoked
potentials and biomechanical data. Some of the software packages I have used include Matlab,
LabVIEW, BodyBuilder (Vicon) and SPSS. More recently, my research has more specifically focused on
studying physical activity in individuals with lower extremity amputations. The number of steps taken per
day, along with duration spent, walking, standing, sitting or lying were quantified using wearable sensors.
In addition, I have also published a review on factors that affect PA levels in individuals with amputations.
