Author Profile
Education and Training
Dr. John M. Carethers began his academic journey at Wayne State University, Detroit, Michigan, where he earned a B.S. in Biological Sciences with a minor in Chemistry (1981–1985). He continued at Wayne State University School of Medicine, graduating with High Distinction with an M.D. in 1989. He then completed an Internship (1989–1990) and Residency (1990–1992) in Internal Medicine at Massachusetts General Hospital in Boston under the leadership of Dr. John T. Potts. Dr. Carethers pursued a Fellowship in Gastroenterology at the University of Michigan Medical Center from 1992 to 1995 and simultaneously engaged in postdoctoral research training under Dr. Stephen J. Weiss. From 1993 to 1995, he worked as a research-track fellow in the laboratory of Dr. C. Richard Boland, focusing on the genetics and mechanisms of cell death in colon cancer. He further expanded his leadership skills through several executive programs, including the AAIM Executive Leadership Program at Harvard (2005), UCSD Physician Leadership Academy (2007–2009), AAMC Council of Deans Fellowship (2015–2016), and the Big Ten Academic Alliance Leadership Program (2018–2019).
Research Interests
Dr. Carethers is internationally recognized for his work in colorectal cancer research. His areas of expertise include mechanisms of tumor progression, tumor genetics, and tumor markers. He has conducted extensive studies on DNA mismatch repair, molecular pathology, and microsatellite instability. His work also addresses familial cancer syndromes, disparities in colorectal cancer outcomes among minority populations, and strategies to improve colorectal cancer screening—especially in early-onset cases.
Honors and Awards
Dr. Carethers has received numerous prestigious awards and honors throughout his career. Notably, in 2023, he was the Commencement Keynote Speaker at Stonybrook University Renaissance School of Medicine and was honored with the naming of the “John Carethers, MD Conference Room” at the University of Michigan. He was elected Vice-President of the American Clinical and Climatological Association (ACCA) and became a member of the Blue Ridge Academic Health Group (BRAHG). In 2024, he was inducted as a Fellow of the American Association for Cancer Research (FAACR) and received the Recognition Award at the 10th Annual Cancer Health Disparities Symposium hosted by SUNY Downstate Health Sciences University.
Memberships and Professional Activities
Dr. Carethers is deeply involved in academic leadership and professional mentoring. He has served as a mentor for Research Scholar Awardees from the University of Kansas and Duke University. He was part of the AGA’s DDW Abstract Review panel (2023), chaired the AGA Recognition Prize Selection Committee (2023–2024), and served on the AGA Leadership Pathways Task Force (2024–2025). His commitment to addressing social determinants of health was evident as he spoke at the DDW session on Food Insecurity and Colon Cancer in Washington, D.C., in May 2024. Additionally, he is a reviewer for the GI Opportunity Fund and continues to engage in collaborative efforts to enhance colorectal cancer screening strategies, including with Exact Sciences.
