Education and Career

Dr. Frey is Associate Professor at the Department of Psychiatry and Behavioural Neurosciences at McMaster University, Academic Head of the Mood Disorders Program, and Director of the Women’s Health Concerns Clinic at St. Joseph's Healthcare. He completed his M.D. and specialization in Psychiatry at the Federal Medical School of Porto Alegre, Brazil, and his M.Sc. and Ph.D. in Biochemistry at the Federal University of Rio Grande do Sul, Brazil. Dr. Frey completed a Research Fellowship at The University of Texas Health Science Center at San Antonio, working with brain imaging in bipolar disorder. Subsequently, Dr. Frey did a Postdoctoral Fellowship in brain imaging at the Montreal Neurological Institute (McGill University), where he conducted a PET imaging study correlating serotonin synthesis and 5HT1A receptor binding in the human brain. In 2008, Dr. Frey received a CIHR postdoctoral fellowship award to study brain imaging in perimenopausal women with depression, under supervision of Dr. Claudio Soares and Dr. Meir Steiner at the Women’s Health Concerns Clinic, St. Joseph’s Healthcare Hamilton. Dr. Frey is also a previous recipient of a fellowship award from Father O’Sullivan Research Centre (SJH).

Research Interests

Dr. Frey is interested in understanding the cerebral mechanisms involved in the neurobiology of bipolar and major depressive (unipolar) disorder, with an emphasis in female-reproductive life events. He is co-investigator and site–PI of a multicentre study investigating biomarkers of treatment response in depression (www.canbind.ca) sponsored by the Ontario Brain Institute, CIHR and the Ontario Ministry of Research and Innovation. He is the principal investigator of a new study sponsored by the Brain & Behavioral Foundation (formerly NARSAD) investigating cortical myelin in individuals with bipolar disorder. He is also PI of an fMRI study of brain correlates of emotional regulation in women with co-morbid bipolar and premenstrual dysphoric disorder funded by the Ontario Mental Health Foundation and J.P. Bickell Foundation. Dr. Frey is also involved in a number of projects investigating the role or biological/circadian rhythms in the development of postpartum depression and anxiety. He has had more than 80 publications accepted in peer-reviewed journals and has presented his work in numerous national and international conferences. In addition, he supervises graduate and undergraduate students in various research projects.

Clinical/Education Interests

Dr. Frey is staff psychiatrist at the Women’s Health Concerns Clinic and the Mood Disorders Program at St. Joseph's Healthcare Hamilton. His clinical/educational interests involve teaching residents, medical students and fellows in the assessment and treatment of individuals with bipolar disorder and depression, as well as mood disturbances associated with premenstrual phase, pregnancy, postpartum and menopause transition.
