John Rolston, MD, PhD

Dr. John Rolston is a neurosurgeon and neuroscientist at Brigham & Women’s Hospital and Harvard Medical School. Clinically, he specializes in epilepsy surgery—including laser ablation, deep brain stimulation (DBS), and responsive neurostimualtion—and movement disorders, including DBS and focused ultrasound. Dr. Rolston received his Bachelor’s degree in computer science from Columbia University, before studying brain-computer interfaces for epilepsy during his PhD at the Georgia Institute of Technology and Emory University. He received an MD from Emory University before completing his residency training in neurosurgery at the University of California, San Francisco.

Aaron Warren, PhD

Aaron Warren completed a PhD in epilepsy neuroimaging at the University of Melbourne, Australia, using functional brain mapping to localize seizure networks in pediatric epilepsy, with a particular focus on Lennox-Gastaut syndrome. In his postdoc, Aaron is using MRI and electrophysiologic methods to optimize neurosurgical treatments including deep brain and responsive neurostimulation.

Zoé Dary, PhD

Zoé Dary completed her PhD in Cognitive Neuroscience at the University of Aix-Marseille, France, where she investigated the neural and multisensory basis of bodily self-consciousness. As a postdoctoral researcher, she is using electrophysiological techniques to study Lennox-Gastaut syndrome and explore key aspects of self-perception.

Aryan Wadhwa, BA

Aryan Wadhwa is an MD student at Boston University School of Medicine. He received a B.A. in Medical Sciences from Boston University’s Seven-Year Liberal Arts/Medical Education program. Under Dr. Rolston, he is investigating the effects of deep brain stimulation on non-motor symptoms, as well as exploring possible mechanisms of pediatric epileptic lesion development.

Niels Pacheco-Barrios, MD, MSc, MMSc(c)

Niels Pacheco is a physician from Peru currently pursuing a master's degree in Biostatistics at Harvard Medical School. Under the mentorship of Dr. Rolston, he is exploring the interaction between circadian rhythms and the clinical outcomes of various neuromodulation therapies, including Deep Brain Stimulation and Responsive Neurostimulation. Alongside his research, Niels is deepening his expertise in computational neuroscience and dynamical systems, with a focus on their applications in clinical neuroscience.

Adam Glaser, MD

Adam Glaser is a PGY-5 neurosurgery resident at Mass General Brigham (Brigham and Women's Hospital / Boston Children's Hospital). He completed his M.D. at Dartmouth. He is completing an NIH T32 postdoctoral training fellowship through the MGH Center for Neurotechnology and Neurorecovery under Dr. Rolston’s mentorship. He was also awarded the 2026 AANS/CNS Pediatric Section Resident Traveling Fellow, working on a project jointly supervised by Dr. Rolston and Dr. George Ibrahim at The Hospital for Sick Children to predict response to responsive neurostimulation from preoperative imaging. Adam's interests center on pediatric epilepsy surgery and neuromodulation for drug-resistant epilepsy.

Michaela Stamm, MS

Michaela Stamm is a research assistant for the MEND lab. They received a B.A. in Neuroscience from Smith College, and an M.S. in Cellular and Molecular Biology from Tulane University. With Dr. Rolston, they are focused on developing comprehensive and accessible ways to better obtain, organize, and store clinical data, along with navigating regulatory processes.
