Biography
Hamilton was born into a family of Oregon educators. After growing up in the Portland area, he attended Occidental College and completed his bachelor's degree in literature and writing at the University of Oregon. He earned his M.D. from Oregon Health and Science University in 1977. He completed psychiatry residency at the Karl Menninger School of Psychiatry and served on the faculty there for two years before returning to Oregon Health and Science University, where he taught psychotherapy for more than a decade and became Associate Professor of Psychiatry. In 1997 he co-founded Physicians for Compassionate Care, an organization dedicated to promoting education about care for dying patients. He was active nationally and internationally in the debate about whether or not doctor-assisted suicide should be legalized.

He has published three books and numerous articles on psychotherapy. He has also authored articles about the medical ethical controversy surrounding doctor-assisted suicide.

Object Relations Theory and Psychiatry
Hamilton's approach to object relations theory as described in Self and Others: Object Relations Theory in Practice, first published in 1988, was integrative. He originally described object relations theory as having an important place in psychiatry's biopsychosocial model but as not being a complete psychology for the broader field of psychiatry in that it lacked explanations of the effects of physical and cognitive factors on internal and external relationships. In 1996, with the publication of The Self and the Ego in Psychotherapy, he added specific ego functions, including cognitions, and physical factors into the concept of object relations units in an attempt to make object relations theory sufficiently inclusive to serve as a general framework for psychiatry and clinical psychology. Along these lines, he published articles on combining object relations theory and pharmacotherapy as well was object relations and end-of-life decisions.
