Bronte-Stewart Lab Members
Helen M. Bronte-Stewart, MD, MSE
Principal Investigator
The John E. Cahill Professor,
Department of Neurology and Neurological Sciences
Professor, Neurology and Neurological Sciences
Director Stanford Movement Disorders Center
Director Stanford Human Motor Control and Balance Laboratory
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.

Sudeep Aditham
Research Assistant
Sudeep graduated from Emory University with a BS in Neuroscience and Behavioral Biology and a Minor in Philosophy. He did research at a Parkinson’s disease research lab at Yerkes identifying pharmacological treatments that alter brain signals in non-human primates. He has also done research at a translational science primate lab studying infectious disease. At Emory, he was deeply involved with brain injury survivor support, volunteering, and social justice education. At Stanford, Sudeep hopes to deepen his understanding of the neural/kinematic signatures of PD and the evolving role of neuromodulation in patient care. In his free time, he enjoys listening to music, photography, and playing with his dog.
Pranav Akella
Research Assistant
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.
Gary Burnett
Graduate Student
Gary graduated from MIT in 2017 with a B.S. in Electrical Engineering and Computer Science and a B.S. in Brain and Cognitive Sciences. There, he did research in the Biomechatronics Group at the MIT Media Lab using sensor data from a prosthetic ankle to monitor how a patient is walking. He now works as a data scientist at NVIDIA using GPUs to accelerate machine learning workflows in healthcare. Starting in 2020, Gary became a part time Master's Student at Stanford in the Biomedical Informatics department. At Stanford, he hopes to apply his expertise in data science to explore the relationship between neural activity and the kinematics of gait. Outside of work, he enjoys graphic design, music production, weight lifting, and hip hop dance.
Aryaman Gala
Research Assistant
Aryaman graduated from the University of Washington with a B.S. in Neuroscience and a minor in data science. He has prior experience in performing computational and histological analysis to evaluate the efficacy of electrical stimulation in promoting neurorehabilitation after ischemic strokes. He has also worked with eye-tracking and EEG data to identify early biomarkers of autism. At Stanford, Aryaman hopes to understand the neural and kinematic dynamics of Parkinson's Disease and contribute to the optimization of neuromodulation therapies to improve treatment outcomes for patients with movement disorders. Outside of work, Aryaman enjoys playing soccer, listening to music, hiking, and mountain biking.
Shannon Hoffman, PT, DPT
Research Assistant
Shannon is a physical therapist with several years of experience in clinical practice, research, and education at Washington University in St. Louis, Sacramento State, and outpatient rehabilitation centers in Missouri and California.
