Our department achieves high standards of education, research and patient care, all with the goal of bringing the Department of Pathology and Anatomical Sciences to a new level.

I would like to welcome you to the website of the Department of Pathology and Anatomical Sciences within the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo. Whether you are an applicant to one of our programs, a student, resident or fellow here at the school, a pathologist or an anatomist, or just a "surfer", I hope you will find this website interesting and informative as we try to acquaint you with our facilities, our programs and the people who are our staff, faculty and students.

We are a diverse department with Divisions of Pathology and Anatomical Sciences at the medical school campus, four university-affiliated hospital systems, more than 40 full-time and geographic full-time faculty as well as residency and graduate programs. The disciplines of pathology and anatomy, both based on the structure of cells and tissues, are the foundation of almost every clinical specialty. They are at the vanguard of discovery, diagnosis and patient care and they are arguably the most exciting and rewarding of all the fields in medicine and biomedical science. 

The mission of our department is centered around four main areas: education, patient care, research and scholarship and service to the region. Our educational efforts are aimed at medical and dental students, graduate students, residents and fellows. We play a pivotal role in the teaching of the preclinical modules during years 1 and 2 of the medical curriculum. We offer educational programs in both experimental pathology and cell biology at the graduate and postdoctoral levels.

As clinicians, hospital pathologists in the department are dedicated to providing excellent patient care at all the university-affiliated sites. This entails offering a wide range of diagnostic testing and a commitment to continuing improvement.

The department has two main programs of research: 1) the pathological mechanisms that are the basis of disease and 2) the structural and signaling mechanisms that provide highly specialized functional capabilities for cells and tissues. These interests span a broad range of topics including oncology, endocrinology, cell biology and neuroscience. Research projects in the department focus on both applied and basic experimental work.

Community Service

Our faculty believe in our community and many serve in the region as volunteers in various ways. We also view the departmental contribution to the area to comprise education of our citizens, high quality diagnostic services for patients and discovery of new scientific information which will benefit patients and society. As you browse this website, the elements of our mission will be explained in greater detail.
