Residency
Overview
Welcome to the WashU Medicine Department of Pathology & Immunology. One pillar of our department’s tri-part mission is to provide exceptional training to the next generation of pathology and immunology professionals.
From anatomic pathology to clinical pathology to combined anatomic and clinical pathology and more, our residency programs span many areas of pathology, with options to suit all interests. Although initial training is highly supervised, we emphasize acquiring skills that will allow residents to function as confident, independent and highly-effective members of a health care team.

GME consortium requirement for pre-employment screening
The Joint Commission on Accreditation of Healthcare Organization (JCAHO) has clarified HR Standard 1.20 to provide that hospitals are now required to screen trainees in the same manner as staff employed by the hospital if the trainees work in the same capacity as staff who provide care, treatment and services. In order to meet this standard and continue to provide safe, quality patient care and excellent educational opportunities, the GME Consortium has implemented additional screening requirements for trainees. These additional requirements are consistent with the requirements imposed on other employed staff.
House staff paid by Barnes-Jewish Hospital, St. Louis Children’s Hospital and WashU Medicine are required to successfully pass all screening requirements including a drug test and criminal background check prior to beginning their training at this institution. All Consortium policies and procedures governing house staff are available on the GME website.

One of the department’s longstanding traditions is to provide core clinical and research training for individuals planning a career in academic pathology. However, our programs are also well-suited to individuals who plan to pursue careers in hospital- or community-based medical practice.
The goals and aims of the residency program are to:
- Ensure that residents become proficient in core clinical competencies and evidence- and practice-based medicine, while also acquiring essential interpersonal and communication skills
- Train clinically-oriented residents in modern methods of clinical investigation to advance knowledge applied to anatomic pathology and laboratory medicine
- Provide opportunities to participate in sophisticated biomedical research that advances knowledge of the molecular pathogenesis of human disease
Trainees in this department benefit from:
- A high volume of complex as well as “bread and butter” cases
- 55,000 surgical specimens per year
- World-renowned faculty include Louis P. Dehner, MD, a highly gifted general surgical and pediatric pathologist; and Jeffrey I. Gordon, MD, often dubbed “the father of the microbiome”
- Numerous experts in their fields, covering several subspecialties, who are eager to teach residents at the microscope and in informal didactic sessions
- Abundant clinical, translational and basic science research opportunities
- Clinical pathology with resident responsibilities essential to clinical care
- Sign-out of multiple, high-volume next-generation sequencing assays within our in CAP-certified, CLIA-licensed molecular laboratories.
- Exposure to lab management, including a dedicated “Pathology Management” lecture series and participation in biennial mock-CAP inspections.
- A dedicated desk within the resident room, assigned yearly, which is equipped with a microscope, computer, telephone and filing cabinet.
- An extensive anatomic pathology (AP) and clinical pathology (CP) trainee library within the Residents Room, replenished yearly using a dedicated departmental fund
AP and AP/CP trainees benefit from:
- Sub-specialty sign-out with many internationally renowned surgical pathologists who are eager to teach residents at the microscope and through formal didactic sessions.
- 10 pathology assistants, 2 biopsy technicians, and one PA student
- A Digital Imaging Center, which scans and stores slides for teaching conferences, personal study sets and research
CP and AP/CP trainees benefit from:
- Direct interaction with clinical providers and laboratory staff to provide consultative, interpretative and test utilization services
- Routine high-complexity test sign-out as a part of hematology, clinical chemistry, clinical microbiology and molecular rotations
- Experience in high-throughput testing and total laboratory automation within the clinical chemistry and clinical microbiology laboratories
- Primary management of a robust in-patient apheresis consult service
- Hands-on training in clinical informatics, machine learning and quality improvement as part of a dedicated, longitudinal pathology informatics course

Mentoring opportunities
Anatomic pathology and laboratory medicine residents work closely with department faculty in one-on-one interactions involving interpretation and diagnosis of autopsies and surgical specimens and in clinical laboratory diagnosis. All residents are encouraged to seek the ongoing counsel of their faculty advisors in selecting curricular options, in designing elective activities and in career planning. Residents also are strongly encouraged and provided ample opportunities to undertake in-depth investigative activities with any individual faculty mentors. Residents who aspire to academic careers in basic scientific investigation will develop long-term mentoring relationships with WashU Medicine scientists in whose laboratories they undertake postdoctoral research training.

Testimonial
“I chose WashU Medicine in St. Louis for my pathology residency because of the exceptional faculty, the breadth of research opportunities, the outstanding clinical training, and the diverse group of residents and fellows who I now gladly call friends. At every turn, I have been impressed by the depth of knowledge and experience among both faculty and trainees. Although many of the faculty are leaders in their fields, they do not hold this as a point of pride but rather as an opportunity and even a mandate to pass on this knowledge to others. I feel fortunate to be part of the WashU tradition and benefit from so many great teachers and mentors. All said I couldn’t be happier with my experience in St. Louis and my time at WashU!”
