Infectious Diseases Fellowship

Thank you for your interest in our UC Davis Infectious Diseases Fellowship.

We are proud to say the Department of Infectious Disease's has been a key area of investigation since the founding of UC Davis Health. Our founding chief, Paul Hoeprich, M.D. wrote the first comprehensive textbook on Infectious Diseases.

In the late 1980s and the 1990s, UC Davis scientists, including faculty from the Division of Infectious Diseases, played important roles in understanding HIV infection, AIDS, and other retro-viral infections by identifying simian and feline immunodeficiency viruses.

Our faculty, along with others at UC Davis, advanced knowledge of the natural history of both the AIDS viruses, including mechanisms of cross-species transmission and the role of the immune systems in fighting these viruses.

Our current division chief, Dr. Stuart Cohen, is a leading expert in the pathogenesis and epidemiology of Clostridium difficile disease, and the first-author of the current IDSA C. difficile guidelines. Former program director, Dr. George Thompson, is the second-author of the 2016 IDSA Aspergillosis guidelines, and the 2020 Endemic Mycoses guidelines.

Please consider applying for our program, as there are many excellent specialty training programs that boast dedicated faculty & residents along with advanced clinical care systems. Not only is UC Davis a great program, but it is also a great place to live – (Take a glance at our Sacramento Campus!)

While we are proud of our program’s unique accomplishments, the number one reason to come here is the people. We have a wonderful group of fellows, an incredible group of distinguished faculty, and supportive, friendly administrators and staff who all strive to help you make the most out of fellowship training.
