Sarah Andres, Ph.D.

  • Assistant Professor of Pediatrics, Division of Gastroenterology, School of Medicine


Dr. Andres has a long-standing interest in translational research centered on cellular and molecular mechanisms of gastrointestinal homeostasis and disease.  She is particularly interested in extracellular vesicle-mediated communication and post-transcriptional regulation within the GI tract and throughout the body during homeostasis, inflammation, and cancer. In addition to contributing to the scientific community through research, Dr. Andres is a passionate about mentoring and loves to help her trainees succeed in her lab and beyond.
