Meet The Faculty

Pathology faculty members look through microscopes in a classroom at Mayo Clinic

The Department of Laboratory Medicine and Pathology at Mayo Clinic in Arizona is part of a growing, internationally-recognized academic medical center set in the beautiful Sonoran Desert. It is one of the three main United States sites of Mayo Clinic, in addition to Rochester, Minnesota, and Jacksonville, Florida. Mayo Clinic in Arizona is a unique and growing practice environment, focused on the needs of the patient and dedicated to teamwork. A highly skilled team of medical professionals including physicians, scientists, medical technologists, medical technicians, lab assistants, biologists, chemists, microbiologists, geneticists, and other specialists provide high-level care for many. The department receives specimens for testing from Mayo Clinic and is a growing part of the Mayo Clinic reference laboratory for other clinics and hospitals, both nationally and internationally.

The ongoing Mayo Clinic campaign titled “Arizona. Bold. Forward.” commits $750 million to double the size of the Phoenix campus and add 1.4 million square feet to the campus by 2024. Mayo Clinic in Arizona is consistently ranked No. 1 in the state of Arizona by U.S. News & World Report’s Best Hospitals. Mayo Clinic in Arizona is a top-ranked medical school and is also affiliated with Arizona State University.

The Division of Anatomic Pathology has 21 pathologists, with specialty expertise covering the entire field of surgical pathology. The division is organized around groups dedicated to specific organ systems, but all members contribute to general areas, such as frozen section service, autopsy, and cytology. The division is supported by a full-service histology and immunohistochemistry laboratory. Most molecular testing is performed at Mayo Clinic in Rochester, with whom we partner closely.

From the program directorRish K. Pai, M.D., Ph.D.

Welcome to our Gastrointestinal and Liver Pathology Fellowship website! We hope this website will be informative, but please feel free to email me with any questions.

The mission of our fellowship is to train pathologists to become experts in understanding and diagnosing routine, complex, and esoteric pathologic specimens from the gastrointestinal tract and liver; become consultants to other pathologists on these cases; and advance the science of gastrointestinal and liver pathology through clinical and transitional research.

While at Mayo Clinic, you will be exposed to a large academic surgical pathology practice, many research and teaching opportunities, and faculty dedicated to your educational success.

Sincerely,

Rish Pai, M.D., Ph.D.
Gastrointestinal and Liver Pathology Fellowship Director
