Current Trainees
The Oliver Langenberg Physician-Scientist Program has 33 active trainees, each at different stages of their pathway from medicine intern to research fellow. Their medical disciplines are in nine different sub-specialties within the Department of Medicine.
The current PSTP trainees participate in semi-annual meetings with the directors, as well as monthly work-in-progress seminars throughout the academic year. The senior PSTP Fellows present their research among their peers and directors at the annual PSTP Symposium.
