Dr. Jonathan Leong Mates, MD

About Me

I grew up in San Francisco, spent a few years in Los Angeles for undergraduate training, and went to medical school at University of California, Davis. I then left California for the cold of the Midwest for residency at Henry Ford Hospital in Detroit, Michigan. I completed my training in Pittsburgh, Pennsylvania, working in Abdominal Imaging as well as Radiology Informatics. I am now happy to be back home in California with my family. I started working at Kaiser Permanente at Walnut Creek in 2005 as a general radiologist.

I am very interested in imaging informatics, which focuses on using systems (primarily technology) to improve access to and better utilize imaging information for the solving of medical problems. This is a natural outgrowth of my undergraduate training in anthropology and my experience in the computer-heavy field of radiology. I see myself as a bridge between the technical side of medicine and the people who actually have to use the technology.

I chose the …Kaiser Permanente system because I knew of its work on using technology to improve patient care and its emphasis on evidence-based medicine. It is the perfect place for me to work in my two chosen areas of interest.
