Nitin Sharma, PhD

Professional Biography: Nitin Sharma received the B.E. degree in Industrial Engineering from Thapar Institute of Engineering and Technology, India, in 2004, and the M.S. degree and the Ph.D. degree in Mechanical Engineering from the Department of Mechanical and Aerospace Engineering, University of Florida, Gainesville, in 2008 and 2010 respectively. He was an Alberta Innovates-Health Solutions Post-Doctoral Fellow with the Department of Physiology, University of Alberta, Edmonton, Canada. From 2012-2017, he was an Assistant Professor with the Department of Mechanical Engineering and Materials Science, University of Pittsburgh, and promoted to an Associate Professor in 2018. In 2019, he joined the Joint Department of Biomedical Engineering at North Carolina State University-Raleigh and University of North Carolina-Chapel Hill. He has won O. Hugo Schuck Award for the Best Application Paper from the 2008 American Control Conference. His research in hybrid exoskeletons is funded by NSF awards and NIH. His awards include NSF CAREER Award in 2018, IEEE Control Systems Technology Award 2019, and NIBIB Trailblazer Award in 2021.

Research Interests: His research interests include the modeling, optimization, and control of functional electrical stimulation (FES), hybrid exoskeletons that combine FES and a powered exoskeleton. His research group has recently started looking into using ultrasound imaging-derived sensing signals to address human-robot interaction problems in rehabilitation.
