PSTP People

The PSTP currently consists of a mix of interns, residents, and fellows of all different levels and subspecialties. The current subspecialty matrix crosses the areas of hematology-oncology, gastroenterology, endocrinology, rheumatology, infectious diseases, and pulmonary critical care medicine.

In past years graduates of the PSTP have, by and large, pursued academic medical careers in a variety of areas, including the National Institutes of Health (NIH).
