Brandon J. Cornejo , M.D., Ph.D.

  • Associate Professor of Psychiatry, School of Medicine
  • VA Staff Psychiatrist
  • VA TMS Clinic Director


Behavioral Health and Neurosciences Division at the VA Portland Health System (VAPORHCS). Dr. Cornejo is an adult psychiatrist who has worked in both inpatient and outpatient settings and has been extensively involved with training both residents and medical students. His primary focus is as an interventional psychiatrist using transcranial magnetic stimulation (TMS) to address psychiatric illness.

Dr. Cornejo is currently the clinical director of the TMS service at the VAPORHCS. He and his team use TMS to treat veterans with treatment resistant depression. In addition to this work, he also sees adult veteran outpatients in Bridge Clinic, a service directed at new patients entering the Portland VA system. He has been extensively involved with teaching and has mentored dozens of residents and medical students. He is now the clinical rotation director for the neuromodulation rotation at OHSU aimed at senior psychiatry residents and fellows.

From a research perspective, he collaborates with other faculty on several research projects including investigations of TMS modulation of cue-induced methamphetamine craving and, in another line of inquiry, modulation of impulsivity and suicidal ideation using accelerated TMS, a form of TMS where multiple treatments are administered in a shorter period of time. Dr. Cornejo has been successful in finding foundational funding to continue to explore these areas of interest.

In addition to his clinical, teaching and research activities, Dr. Cornejo is a member of the Clinical TMS Society and has served on committees focused on the development of delivery of improved care for veterans. He has been an active member of the Institutional Review Board (IRB) for multiple years.
