Benjamin D. Greenberg is a Professor of Psychiatry and Human Behavior at Brown University, with affiliations at Butler Hospital and the Providence VA Medical Center's Center for Neurorestoration and Neurotechnology (CfNN). He holds a BA in Psychology from Amherst College, a PhD in Neurosciences from UC San Diego, and an MD from the University of Miami, with specialized training in neurology (Columbia University) and psychiatry (Johns Hopkins Hospital).

• Developed surgical and noninvasive brain stimulation treatments for OCD and related conditions
• Co-Director of NIMH-funded Translational Research Centers on OCD brain circuitry
• Pioneered deep brain stimulation (DBS) and gamma knife capsulotomy trials for intractable OCD
• Current focus on TMS, tDCS/tACS, and focused ultrasound for PTSD and chronic pain

His research integrates brain stimulation (DBS, TMS, tDCS), neuroimaging, and cognitive neuroscience to understand and treat neuropsychiatric disorders. Recent work explores functional connectivity modulation in PTSD and OCD via combined tDCS/virtual reality and computational modeling of lesion networks. He has led multicenter trials and developed patient-specific connectomic models for DBS outcomes.

Publications span OCD genetics, neurostimulation mechanisms, and cross-disorder analyses with Tourette Syndrome. Collaborations include neurology, psychiatry, and biomedical engineering teams at Brown University, Johns Hopkins, and the NIH.
