GI/Liver Pathology Fellowship


The Gastrointestinal and Liver Pathology Faculty Assistant Program is an advanced fellowship that provides training in diagnostic gastrointestinal, liver, and pancreatic pathology. Our case material consists of in-house specimens from Johns Hopkins, as well as cases from our active consultation service. Our faculty members provide specialty experience in gastrointestinal luminal pathology, liver pathology, and pancreatic pathology.

The faculty assistant takes full responsibility for sign-out of in-house luminal gastrointestinal biopsy material and works closely with our faculty members on consult cases. The faculty assistant also participates in clinical conferences and housestaff and medical student teaching. Participation in research is strongly encouraged, and there are multiple opportunities to work with our faculty members on projects.


Three years of AP training or four years of AP/CP training are required. Applicants must have completed their AP training and be AP Board eligible/certified by the July start date. A Maryland medical license is required prior to the starting date. Applicants must have a U.S. permanent resident visa or be a U.S. citizen. A J-1 or H-1B visa is not appropriate for this position.


Applications should be received by July 1 for a July 1 starting date 24 months later (e.g., an application submitted by July 1, 2022 will be for a July 1, 2024 start). Though the deadline for applications is July 1, we encourage you to apply early. Supporting documents should be received within 2 weeks of this deadline (e.g., by July 15, 2022 in previous example).


Please download the application form and send with the supporting documents.

Supporting Documents

  1. A CV with bibliography
  2. A brief discussion about your interest in gastrointestinal pathology and your longer-term career plans.
  3. Four (4) original letters of recommendation: one from your current department chairperson or other superior, and three others from persons of your choosing.
    These letters should be addressed and emailed directly to the program directors separately by the persons making the recommendations.
