Sarah Puryear, MD, MPH


I am an infectious disease (ID) physician and clinical researcher whose work focuses on the intersection of alcohol, HIV, and tuberculosis in sub-Saharan Africa. I am currently an assistant professor in the Division of HIV, ID, and Global Medicine at the University of California, San Francisco (UCSF). I am trained in infectious diseases, HIV and TB prevention and epidemiology, and work as a physician in the Ward 86 HIV clinic and the inpatient Internal Medicine and HIV/ID consult services at San Francisco General Hospital.

Zoe Quandt, MD

Assistant Adjunct Professor
Diabetes Center

Dr. Quandt is an endocrinologist at UCSF and the San Francisco VA with particular interest in endocrine autoimmune disease like type 1 diabetes and endocrine complications of cancer treatments, particularly immunotherapy. She does clinical and translational research trying to better understand who gets these complications and why. She is the clinical lead for adults eligible for teplizumab, an immunotherapy approved to delay the onset of type 1 diabetes.

Isabel Rodriguez-Barraquer, MD, PhD, MHS

Assoc Professor In Residence

My research focuses in applying novel epidemiological and statistical methods to understand the dynamics of infectious diseases and inform control interventions. While I am interested in infectious diseases generally, most of my work has focused on understanding shifts in the epidemiology of vector borne diseases including dengue, leishmaniasis, chikungunya, malaria and Zika.

Rachel Rutishauser, MD, PhD

Assoc Professor In Residence

I am an infectious disease-trained Associate Professor of Medicine in the Division of Experimental Medicine at the University of California, San Francisco. My laboratory focuses on understanding the mechanisms that promote the formation of effective and durable CD8+ T cell immunity to viral pathogens (e.g., HIV, SARS-CoV-2) and vaccination at different stages of human development.

Tiffany Scharschmidt, MD

Associate Professor in Residence

I am a dermatologist, microbiologist, and immunologist and currently serve as an Associate Professor of Dermatology. I dedicate 80% of my time to research and the remaining time taking care of patients with severe inflammatory skin diseases. The central focus of my laboratory is to investigate the cellular and molecular mechanisms that mediate interactions between bacteria and the developing immune system, with a long-term goal of developing new therapeutic approaches based on this knowledge.

Autoimmune rheumatic diseases, which constitute a broad range of chronic illnesses, cause significant morbidity and mortality in the US and worldwide. T cell receptor (TCR) recognition and signaling have long be recognized to play a critical role in the pathogenesis of autoimmune diseases. However, how altered TCR signaling strength affects immune tolerance and promotes autoimmunity remains incompletely understood. Dr.
