Dr. Garrett is the inaugural recipient of the ASCI / Marian W. Ropes, MD, Award, for her scientific contributions to the understanding of diseases related to perturbations in the balance between the immune system and microbiome.

Dr. Garrett founded the Harvard Chan Microbiome in Public Health Center and co-leads a Cancer Research UK Grand Challenges Award — including more than 100 North American and European researchers — to study colon cancer and the gut microbiome. As associate director of the immunology graduate program at Harvard Medical School, she has taken on leadership roles for diversity, equity, inclusion, and belonging — as a mentor for women and postdoctoral fellows underrepresented in biomedical sciences.

Dr. Garrett received her BS, MS, MD, and PhD from Yale University. She completed her clinical residency at Brigham and Women’s Hospital and fellowship at Harvard Medical School and the Dana-Farber Cancer Institute; her research fellowship was at the Harvard T.H. Chan School of Public Health (HSPH). She is Irene Heinz Given Professor of Immunology and Infectious Diseases at HSPH and professor of medicine at Harvard Medical School.
