Physician Founder

Kevin P. Muthu, MD

Harvard-Trained Interventional Neuropsychiatrist

When conventional treatment stalls, the missing piece is often not another medication. It’s a deeper understanding of the brain’s circuitry and a clinician trained to modulate it. MUTHU Brain Medicine was founded to gain that understanding, and Dr. Muthu trained to be that clinician.

DIRECTOR OF INTERVENTIONAL PSYCHIATRY*

Appointed Director of Interventional Psychiatry within the largest municipal hospital system in the country, serving over one million New Yorkers annually. This role brings precision TMS and ECT services to one of the nation’s most diverse and underserved patient populations.

Chief Resident of Neuromodulation

Selected as Chief Resident of Neuromodulation by the faculty of the Harvard Medical School Affiliate Psychiatry Residency, VA Boston. Led the neuromodulation house-staff service, coordinating TMS, ECT, and ketamine infusion programs while mentoring residents in circuit-based psychiatry.

The Philosophy

The science of a second chance

Traditional psychiatry speaks in the language of chemistry. Interventional neuropsychiatry speaks in the language of circuits, the electrical networks that shape mood, attention, and the way we move through the world. When depression, anxiety, or ADHD becomes “treatment resistant,” it is rarely because a patient is broken. More often, specific brain circuits have quieted, drifted, or become stuck.

At MUTHU Brain Medicine, our work is to locate those circuits precisely and give them the right kind of nudge with careful, deprescribing-first psychopharmacology, with neuromodulation, and with the lifestyle scaffolding that lets neuroplasticity actually take root. The goal isn’t to add another prescription to your list. It’s to restore functional connectivity between your brain’s emotional centers and its executive control, and hand you back the agency to lead your life.

Training & Certification

Trained where interventional psychiatry was pioneered

A deliberate constellation of programs across TMS, ECT, and ketamine, chosen for the depth and specificity each one offers.

Brigham & Women's Hospital — Center for Brain Circuit Therapeutics

TMS Training Program (Harvard Medical School)

Training with the group that pioneered lesion network mapping and fMRI-guided TMS targeting, methods that are foundational to modern precision psychiatry. Hands-on experience across FDA-approved depression protocols (standard rTMS, iTBS, SAINT-style accelerated, deep TMS), M1 rTMS for chronic pain, and mPFC targeting for anxious depression.

McLean Hospital — TMS Service

Harvard Medical School Teaching Hospital

Longitudinal TMS training at McLean, established in 1811, one of the oldest psychiatric institutes in the United States and consistently ranked among the top hospitals in America. Trained under Dr. Shan Siddiqi and Dr. Josh Brown across MagVenture, BrainsWay, and NextStim platforms, with neuronavigation-guided TMS and circuit-based targeting protocols.

McLean Hospital — ECT Service

One of the largest ECT services in the country

Trained with McLean's ECT service, which delivers over 10,000 treatments annually. Personally administered 100+ supervised ECT treatments across treatment-resistant depression, psychotic depression, catatonia, treatment-resistant mania and psychosis, autism-associated self-injury, and agitation in dementia. Gained fluency across ultra-brief, near ultra-brief, and brief-pulse protocols and all major electrode placements.
