Dr. Helen Bronte-Stewart is the John E Cahill Family Professor in the department of Neurology and Neurological Sciences. She is a neurologist, neurophysiologist and movement disorders specialist, who has used her training in mathematics and physics, bioengineering, neurology, movement disorders, and single unit electrophysiology in primates to develop a rigorous translational program in motor control research in human subjects with movement disorders. Dr. Bronte-Stewart is the Director of the Stanford Comprehensive Movement Disorders Center, the Co-Director of the Stanford Balance Center, and the Division Chief of Movement Disorders in the department of Neurology and Neurological Sciences. She directs the Stanford Human Motor Control and Balance Laboratory, where she has developed computerized, quantitative measurements of motor behavior, which are being implemented in a wide range of Movement Disorders. Her research investigates the brain’s contribution to abnormal movement in human subjects, using synchronous brain recordings and quantitative kinematics, and how these are modulated with different frequencies and patterns of neurostimulation. Dr. Bronte-Stewart’s team was the first in the United States to implant a sensing neurostimulator, from which they can record brain signals directly, and use the patient’s own neural activity to drive the first closed loop neurostimulation studies in Parkinson’s disease. This work has led to the first multicenter national clinical trial in closed loop deep brain stimulation for people with Parkinson’s disease, which Dr. Bronte-Stewart will lead. Dr. Bronte-Stewart's passion for understanding how the brain controls movement comes from a background in classical and modern dance.

Pranav holds an Sc.M. in Biotechnology from Brown University and a B.S. in Bioengineering (Biotechnology) from UC San Diego. His Master's thesis centered around developing a machine learning algorithm that modulated deep brain stimulation parameters to reduce power in the beta band of Parkinson's Disease patients. To aid in his thesis research, Pranav interfaced with Parkinson's Disease patients intraoperatively and helped develop communication software between two systems involved in modulating the deep brain stimulation parameters. Prior to graduate school, Pranav worked as a regulatory medical writer and manufacturing associate where he developed an interest in creating integrated systems that would aid in biological research. During his undergraduate studies, he built an interest in research through his work UC San Francisco, where he studied biomechanics in the School of Dentistry, and his work at UC San Diego, where he studied cartilage tissue engineering in the Jacobs School of Engineering. At Stanford, Pranav wants to further his understanding of neural and behavioral variables that can be used to alleviate parkinsonian symptoms in PD patients. In his free time, he likes to hike, sing, and travel.
