Welcome to Our Division

Now more than ever, Infectious Diseases are changing the way we live. A worldwide pandemic, life threatening emerging infections like Ebola, and multidrug resistant bacteria are challenging us to find therapies and algorithms to deal with these new problems. Yet, seldom has there been a more exciting time in translational medicine. Together, clinicians and scientists have brought forth diagnostics and therapeutics to combat a pandemic in record time. Phages are used to treat pan-resistant microbes and fecal microbiota and gene therapy are successfully healing intractable diseases. Infectious disease physicians play a major role bridging basic science and clinical medicine to expand our understanding of infections and bring novel therapies to patients with complex diseases.

At UCSD Dept. of Pediatrics and Rady Children's Hospital, we invite you to join the fight and help lead the way as we bring cutting-edge therapeutics to children with infection.

Program Highlights 


UC San Diego School of Medicine awarded $6.1M

to study effects of maternal antibiotic use on infant health in new collaborative research center funded by National Institutes of Health. The research team includes division members Adriana Tremoulet (lead PI), Victor Nizet, George Liu, Pieter Dorrestein, and Brookie Best.


New T32 Awards

The overarching goal of the CARING T32 training program is to train MD and PhD scientists who wish to pursue rigorous research training that will place them on the pathway to productive, independent academic research careers. The new T32 Training Grants awarded to UCSD Pediatrics will be used towards supporting Fellow research.


Dr. Victor Nizet has been elected to the National Academy of Medicine

Dr. Nizet is recognized for his contributions to mechanisms of pathogen virulence, innate immune defense, and antibiotic resistance.


Patient Care

Patient care is based at Rady Children’s Hospital San Diego, a nonprofit, 524-bed pediatric-care facility that provides state-of the art tertiary as well as quaternary care. The medical center has over 18,000 admissions per year and provides pediatric medical care to San Diego, Riverside, Imperial and Orange Counties.
