About
Overview
Since its inception in 1910, our department has demonstrated combined excellence in research, training and clinical service. Our conviction that basic science research leads to exceptional training and high-quality clinical service has made our department a vital bridge between the basic sciences and other clinical disciplines at WashU Medicine. We are an ever-evolving group of scholars dedicated to human pathobiology and the care of those afflicted with disease.
Divisions
We showcase our commitment to excellence across a spectrum of specialized research areas, each dedicated to advancing our understanding of disease through cutting-edge diagnostics and innovative treatments. Here, we unite diverse expertise to forge new paths in medical science.
Although examination of tissue by light microscopy continues to be the fundamental diagnostic technique in anatomic pathology, the Division of Anatomic and Molecular Pathology uses several other laboratory diagnostic methodologies, including Immunohistochemistry, electron microscopy, flow cytometry and molecular genetic testing.
The Division of Genomic and Molecular Pathology is dedicated to developing and delivering innovative genomic assays for oncology, inherited disorders, and other genetic diseases. Through cutting-edge diagnostics and translational research, we enable precision medicine and help ensure patients receive the most informed and effective care. The Division is home to ACGME-accredited fellowships in Laboratory Genetics and Genomics and Molecular Genetic Pathology.
With its 14 basic science laboratories, including 4 led by members of the National Academy of Sciences and one Howard Hughes Medical Investigator, the Division of Immunobiology is internationally recognized for its key discoveries in immunology.
Home to 17 basic and clinical research laboratories, the Division of Laboratory and Genomic Medicine is at the forefront of test development and application, particularly in the fields of genomics, epigenomics, and proteomics.
By integrating modern techniques and insights gleaned from new developments in basic molecular neuroscience research, the Division of Neuropathology is committed to the advancement of the clinical practice of diagnostic neuropathology.

Pioneers in pathology and laboratory medicine
In addition to a century-long focus on the relationship between the basic science of immunology and disease, the department is one of the major centers for academic pathology and laboratory medicine in the nation. Its divisions have played major and pioneering roles in surgical pathology and laboratory medicine.
Our faculty enthusiastically embraces its responsibility to train the next generation of medical scientists and clinicians. We offer contemporary and comprehensive training programs for graduate students, postgraduate trainees, and medical students. Exceptional resources combine with carefully crafted curricula to prepare our trainees to succeed, whether in the competitive world of academic medicine, in cutting-edge basic research or in demanding clinical sub-specialties.
