Current Fellows

2017-2018 Public Psychiatry Fellows


Dr. Kei Yoshimatsu 

Dr. Kei Yoshimatsu was born in Sydney, Australia, spent early childhood in Tokyo, Japan, and then grew up in Los Angeles, California. He majored in Molecular Biology at UCLA, though he much preferred hanging out in the Philosophy department which ended up being his minor. For medical school, he journeyed to rural Minnesota to study at Mayo Clinic where he spent most of his time complaining about the frigid weather! After three years of training at UCSF, Kei is interested in many different areas of psychiatry, including public psychiatry (thinking intersection of trauma, structural violence, and mental illness) as well as psychodynamic psychotherapy (learning about the fascinating workings of the unconscious). In his free time, he will be found in various eateries around SF or wineries around Napa!

Dr. Colin Buzza

Dr. Colin Buzza grew up in Minnesota then attended Wartburg College in Iowa, where he studied biology.  In college, and after he spent time traveling and eventually moved to Edinburgh, Scotland, where he received an MSc in medical anthropology from the University of Edinburgh.  Medical anthropology helped cement his interest in medicine while sparking an interest in psychiatry in particular. After graduation he returned to the Midwest, where he completed an MD/MPH at the University of Iowa.  Experiences in medical school helping to coordinate a free mental health clinic guided his course towards public psychiatry, and this interest helped attract him to UCSF for psychiatry residency.  During residency he has served as an APA Public Psychiatry Fellow and has developed additional interests in advocacy, education, and cultural psychiatry.  Outside of medicine he enjoys cooking, photography, and exploring cities and nature on foot.
