Dr. Francis Loh joined the Department of Medicine in the Division of Hospital Medicine as an Instructor in July of 2025. He was born in Saint Louis and subsequently lived in Japan and New Jersey. He attended Harvard University and graduated with a bachelor’s degree in applied mathematics with a focus on statistics, where he became very interested in principles of decision-making. He returned to Saint Louis and received his medical degree in 2021 from Washington University School of Medicine in St. Louis.
As a medical student, he founded and led a course called “Mental Models in Medicine” for medical students with Dr. Jay Piccirillo, teaching generalizable statistical and decision-making principles to be applied as mental models adapted for clinical reasoning and handling uncertainty. Dr. Loh completed his internship and residency at Barnes-Jewish Hospital/WashU Medicine in 2024. He was recognized with the PGY3 Teaching Resident of The Year Award for exemplary leadership, patient care, and teaching.
He then joined the Division of Internal Medicine in 2024 as Chief Resident at the Barnes-Jewish Hospital/WashU Medicine where he advocated fiercely for resident workflow, quality of life, and educational improvements and taught residents and medical students clinical reasoning. His current areas of interest include general internal medicine with a focus on medical education, clinical reasoning, and helping those around him rise. Outside of medicine, he enjoys spending time with his family (now with a 2 year old son) and friends. His hobbies include tennis, reading, and finding new places to go and to eat at!
