About the Fellowship

The Medical Microbiology Fellowship at Mass General, a one-year, ACGME-approved program, provides advance training to prepare pathologists and infectious disease specialists to serve as directors of a clinical microbiology laboratory. Our graduates possess an in-depth understanding of medical microbiology, including the selection, validation, and interpretation of diagnostic microbiology tests. Our trainees will also be capable of managing a high volume, complex diagnostic laboratory. To these ends, the program will provide a comprehensive curriculum consisting of didactics, rotation through all sections of the clinical microbiology laboratory as well as rotations with various clinical services to gain an understanding of how testing in the microbiology laboratory informs clinical decision making. Particular emphasis will be placed on laboratory operation and management. Graduates of this program may choose to develop an area of research in microbiology that will prepare them for a career as a laboratory director at an academic health center.


Fellows in Medical Microbiology must complete either:

1. Residency training in anatomic, clinical, or combined anatomic/clinical pathology in a U.S. based training program, with primary certification or eligibility by the American Board of Pathology


2. A U.S. primary residence in Internal Medicine or Pediatrics followed by completion of an ACGME accredited fellowship in Infectious Diseases

Applicants must be eligible for a Massachusetts medical license
