Siddhartha Sikdar is currently a professor in the Department of Bioengineering at George Mason University. He is the Director of the Center for Adaptive Systems of Brain-Body Interactions (CASBBI). This transdisciplinary center includes faculty with expertise in engineering, neuroscience and rehabilitation. The vision for CASBBI is to improve the function and quality of life of individuals living with physical and psychosocial disability through research on mechanisms and modulation of complex adaptive systems underlying human movement and behavior.

Sikdar’s research group within CASBBI conducts translational research using imaging to investigate brain-body interactions in a number of clinical conditions of major public health significance, such as chronic pain, stroke, spinal cord injury, and amputation. The group uses state-of-the-art ultrasound and laser instrumentation for developing new ultrasound, optical, and hybrid imaging techniques, and assistive technologies. The group is currently investigating the novel use of wearable ultrasound sensors for sensing muscle activity and controlling external devices such as multi-articulated prosthetic hands and exoskeletons.

Sikdar earned his PhD in Electrical Engineering from University of Washington, Seattle in 2005. He received a postdoctoral fellowship from the American Heart Association. He has been a recipient of the NSF CAREER Award, the Volgenau School of Engineering Rising Star Award, Mason’s Emerging Researcher/Scholar/Creator Award and was nominated for the Rising Star Faculty Award of the State Council of Higher Education in Virginia. His current research is funded by the National Science Foundation, National Institutes of Health, Department of Defense and the Veteran's Administration.
