Welcome to the Bayrer Lab


We are dedicated to the study of intestinal disorders with a focus on how disruption of the gut lining impacts human disease. Our work is multidisciplinary, encompassing the basic science of epithelial cell renewal through integrated physiologic studies. Our imperative is to focus on bench science that will advance new therapies and diagnostics to help our patients in the clinic.


The Bayrer Laboratory is now recruiting postdoctoral scholars!

James Bayrer, MD,PhD
Assistant Professor
Assistant Fellowship Program Director,
Pediatric Gastroenterology


Originally hailing from the desert southwest, I majored in Chemistry and Literature at Claremont McKenna College, where I graduated with honors in both disciplines and the best thesis in science award. I moved to Cleveland to study medicine and pharamcology in the medical scientist training program, completing this in 2007. Along the way I have been fortunate to receive several science awards including the Young Faculty Investigator Award in 2015 from the pediatric gastroenterology society. I enjoy the scientific and clinical environments at UCSF, where I am able to work both with patients and investigate new lines of therapy for gastrointestinal diseases.

My long-term research interests include the study of intestinal epithelial signaling and wound healing. To do this my lab utilizes 3D tissue modeling coupled with animal models of human disease to probe the molecular underpinnings of gastrointestinal disease.

Bayrer Lab Alumni


Pervin Choksi, BS
Graduate Student

Pervin worked with our lab investigating the role of LRH-1 in intestinal epithelial differentiation. She is now persuing her thesis with the Willenbring Lab at UCSF!


Harry Horsnell, BS
Summer Visiting Scholar

Harry joined us from University College London under the prestigous UCSF/UCL rotation project where he worked on questions related to gut-brain signaling. He is now pursuing his dissertation work in the Acton Lab. Good luck Harry!
