Dr. Santosh A. Helekar earned his medical degree (Bachelor of Medicine and Bachelor of Surgery) from the University of Bombay in 1982. He earned a Ph.D. in Neuroscience from Baylor College of Medicine. He held faculty appointments in the Departments of Neurology and Neuroscience at Baylor College of Medicine, Department of Neurology at The Methodist Hospital Research Institute and Weill Medical College (WMC) of Cornell University before rejoining as an associate member of The Methodist Hospital Research Institute in 2007. Dr. Helekar also holds an adjunct faculty appointment in the Department of Biology at Texas A & M University. As a member of the Research Institute Neurosciences Research Program, he directs the Neurophysiology and Neuromodulation Laboratory in the Speech and Language Center of the Department of Neurology, where he conducts neuroscientific research on stuttering, chronic ischemic stroke, motor control, and conscious perception using neuroimaging and magnetic brain stimulation with a new portable wearable device developed by him and Dr. Henning Voss of WMC. He also collaborates with other members of the Research Institute on functional magnetic resonance imaging studies of neurological conditions. Dr. Helekar has been a member of the National Institutes of Health, National Science Foundation, Department of Defense and Alzheimer's Association grant review boards. He has also been an E-print editor of Association for the Scientific Study of Consciousness, and a reviewer for several international research foundations and scientific journals in his fields of interest. He serves on the editorial board of The Open Zoology Journal.

Description of Research

Dr. Helekar's current research program focuses on the development and refinement of multifocal magnetic brain stimulation using a new portable wearable device called Transcranial Rotating Permanent Magnet Stimulator (TRPMS) invented by him and Dr. Henning Voss of Weill Medical College of Cornell University. Ongoing projects in his laboratory involve studying the effects of TRPMS stimulation using brain functional magnetic resonance imaging, positron emission tomography and electrophysiological approaches for application in basic neuroscience research and neuromodulatory therapy in neurobehavioral disorders, including stuttering and chronic ischemic stroke. He is also interested in quantitative functional network-based analysis and theoretical research related to neural processes underlying conscious perception.
