About Us

Welcome to the OHSU Department of Pathology and Laboratory Medicine! 

Pathology and Laboratory Medicine is a dynamic academic department, providing world-class clinical care to our patients, fostering expanded basic science and research programs, innovating pathology education, and pursuing new advancements in patient care, teaching, and research. Using technology such as remote frozen section interpretation, we are improving turnaround times and the work-life balance of our physicians. Our collaborative work environment includes a junior faculty mentorship program, internal leadership opportunities, annual faculty retreat, faculty workgroups, and regular opportunities to share feedback and ideas as we strive for continuous program improvement. Our learners are integral members of our department, and our faculty are passionate educators. Collegiality, collaboration and a love of learning define us as a team of academic physicians and physicians in training.

What is pathology?

Education

We pride ourselves on our enthusiastic, dedicated teachers, the comradery in our learners, and our devotion to the best of academic medicine. We offer an excellent residency program and seven subspecialty fellowships. Our educational offerings also include the unique Pathology Student Fellowship, four medical student electives, and a pathology interest group. Our CME program regularly invites nationally recognized visiting speakers.

Clinical Care

Our pathologists provide exceptional diagnostic care for patients in OHSU Hospital, OHSU Clinics, Doernbecher’s Children’s Hospital, Portland Veterans Affairs Medical Center, and Shriner’s Hospitals for Children. In addition, we offer second opinions for patients as well as consultations for physicians throughout the Pacific Northwest and across the country. Our highly trained, subspecialized providers are devoted to providing state-of-the-art personalized medicine, integrating each patient’s detailed health history to form a precise diagnosis and contributing to the best possible prognosis.

Research

Research and research training are core pillars of the Department of Pathology and Laboratory Medicine at OHSU aligned with OHSU’s missions. Our research program ranges from cutting edge molecular pathology, hematologic malignancies, placental biology and disease, to cardiovascular disease, aging, as well as neurodegenerative disease. The Oregon Brain Bank is also housed in the Department.

Our goal is to understanding pathogenesis of disease, identifying novel diagnostic markers and therapeutic targets for improving patients’ outcome. The department strives to foster a culture that supports collaborations among basic scientists and clinicians on advancing translational discovery programs to facilitate the application of research innovations and discoveries to improve patient care.

Under the leadership of Dr. Guang Fan, Department Chair and Dr. Yabing Chen, Vice Chair for Research, our recent research efforts have focused on advancing digital pathology and promoting the application of machine learning and artificial intelligence in multidisciplinary research collaborations across Pathology and other departments and institutions at OHSU. Our faculty are also committed to research training and education of the next generation of scientists and pathologists, including residents, fellows, medical students, graduate students, and postdoctoral fellows
