General Surgery

Main Content


Part of the mission of the Department of Surgery is the creation of new knowledge, and general surgery residents are actively encouraged to participate in that creation throughout their residency years. Each categorical surgery resident must complete at least one project suitable for publication during the course of his/her training; many residents complete multiple projects within the five years of their training.

Opportunity exists within the general surgery residency for a dedicated one- to two-year research experience for selected residents. Residents may apply for such opportunities and will be chosen by the faculty on the basis of performance within the residency, career goals, and proven intellectual curiosity. Available mentors include the Division of General Surgery physician and research faculty members as well as other faculty across the UMMC campus.

The departmental research faculty welcome residents to their laboratories and will mentor residents to navigate the IRB process. Off-campus dedicated research years will be considered on an individual basis (e.g., NIH Clinical Centers). The timing of the research years within a resident's training may vary and will be individualized.
