He was Assistant Professor of Psychiatry at The University of Massachusetts Medical School with clinical privileges at Marlborough Hospital, a community hospital within the statewide University of Massachusetts healthcare system from 1994 – 2003. His research interests have included psychopharmacology of the treatment-resistant ECT patient; reward pathways in the dopaminergic medial forebrain bundle; and molecular biology research at the National Institutes of Health. He received his board certification from the American Board of Psychiatry and Neurology in 1997 and his recertification in 2007.

Dr. Ellen taught medical students from UMass Medical School during their third-year core clerkship in psychiatry at the Marlborough Hospital site from 1994 to 2003.
