Sara Piva is an associate professor in the Department of Physical Therapy and the Clinical and Translational Science Institute. She is also the founding co-director of the Physical Therapy Clinical and Translational Research Center. Her primary area of research expertise is related to rehabilitation of individuals following total knee arthroplasty. She also leads research on the use of neuromuscular electrical stimulation to reverse muscle atrophy in patients with rheumatoid arthritis and investigates contractile and non-contractile functions of skeletal muscle, including muscle structure and physiology. Piva has a very dynamic research agenda and has received funding from the National Institutes of Health, Patient Centered Outcomes Research Institute (PCORI), and several foundations and professional associations. She has more than 60 peer-reviewed publications in journals of high impact in rehabilitation. She is also active in teaching and has mentored over 20 trainees on research projects. She currently serves on the review boards for peer-reviewed scientific journals and national funding agencies.
