Education and Career

Dr. Frey is Associate Professor at the Department of Psychiatry and Behavioural Neurosciences, and the Academic Head of the Mood Disorders Program, McMaster University and Clinical Director of the St. Joseph's Healthcare Mood Disorders Program and the Women’s Health Concerns Clinic. 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 (Texas), working with brain imaging in bipolar disorder patients. 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-related psychiatric conditions. He is also involved with numerous projects investigating the use of peripheral biomarkers in the course of bipolar and unipolar disorders. In some of his current research projects, Dr. Frey is applying brain imaging techniques (fMRI, MR Spectroscopy and Cortical Thickness Analysis) before and after treatment of perimenopausal women with depression using various antidepressant agents. He is also a co-investigator in a project looking at emotional regulation in offsprings of individuals with bipolar disorder using fMRI. He has had more than 70 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 the Director of the Women’s Health Concerns Clinic (SJH) and the Academic Head of the Mood Disorders Program (CMHS). He is also the Associate Director of the MiNDS Neuroscience Graduate Program at McMaster University. His clinical/educational interests involve teaching residents and medical students 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.
