Matt van de Rijn, MD PhD Pathology, Stanford University School of Medicine, Ludwig Cancer Center Dr. van de Rijn is a surgical pathologist and the Sabine Kohler, MD, Professor of Pathology at the Stanford University Medical Center. His laboratory research focuses on molecular analysis of human soft tissue tumors with an emphasis on leiomyosarcoma. His research has led to molecular classifications of leiomyosarcoma and GIST, among other sarcomas, and to new diagnostic biomarkers, including discovery of DOG1 as a biomarker in GIST. His research has also led to advances in diagnosis and surveillance, particularly using circulating tumor DNA methods. In addition, his lab group has contributed fundamental insights in kinase biology, kinase targeting, and macrophage roles in sarcoma.
