Led the experimental design of 4 studies for the purpose of understanding healthy and impaired gait, as well as for the design biomimetic prosthetic rehabilitation technology▫ Provide first characterization of ankle mechanical impedance during powered push off▫ Expanded knowledge of ankle mechanical impedance to include running, and examined the biomechanical differences between ankle impedance during running and walking ▫ Determine how ankle mechanical impedance during walking is altered by chronic stroke and the implications for rehabilitation strategies and patient care▫ Identify an optimal prosthetic ankle-foot stiffness to minimize compensatory contributions from other lower limb joints across a range of non-steady state walking tasks  Collaborated with practitioners, clinicians, and researchers in a cross-disciplinary team to ensure relevance and accessibility of experimental results Applied system identification techniques to characterize ankle impedance using MATLAB Leveraged impedance data to establish the parameters for a biomimetic impedance controller for robotic prostheses and exoskeletons Adapted published experimental techniques to accommodate unique experimental parameters leading to more accurate data collection for impaired populations and different locomotor tasksWorked with robotic perturbation device and custom variable stiffness ankle-foot prosthesis, providing hardware and software (Python) repairs and modifications as necessary to improve performance.
