Dr. Benicio Frey

Bio

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 (www.stjoes.ca/whcc). He completed his M.D. and specialization in Psychiatry at the FFFCMPA and Federal University of Rio Grande do Sul in 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. Currently, Dr. Frey has over 100 articles published in peer-reviewed journals and his h-index is 31 according to the Web of ScienceTM, and 37 according to Google Scholar.
