Resident Research

Research is an integral part of this residency program.

Apart from research that is done by residents, which they present in local and national meetings, our major research activities include:

  1. Two or three modules of research under faculty mentors
  2. Research mandatory for graduation
  3. Yearly program-sponsored research symposium
  4. Mandatory oral presentations by PGY III
  5. Poster presentations (optional for PGY I-II)

In addition to a personal advisor, each resident is assigned a research advisor who has expertise in his or her area of interest.

Your advisor can help to identify and evaluate research opportunities at Catholic Health, the University at Buffalo, Roswell Park Cancer Institute and Buffalo Veterans Medical Center. Your advisor will also review your progress and guide you as your research progresses.

Out-of-Area Research

If you were conducting a research project outside of Western New York, you may qualify to continue your research at that location. This opportunity is available to residents at all stages of residency.

Research Presentations

Residents are encouraged to publish their results and to present their findings at regional and national meetings including:

  • Austin Flint research Symposium
  • UB Scholarly Exchange Day
  • The New York Chapter of the American College of Physicians (NYACP) state meetings.
  • The Medical Society of the State of New York (MSSNY) annual academic meeting.
