Support the Department of Pathology

Lisa Rimsza, M.D.

Professor of Pathology

Office Address: 



Dr. Rimsza received her medical degree from the University of Arizona in Tucson.  She completed Anatomic and Clinical Pathology residency training at the University of Arizona and her two-year fellowship in Hematopathology at the University of New Mexico in Albuquerque.


Dr. Rimsza is board certified by the American Board of Pathology in Anatomic and Clinical Pathology and subspecialty certified in Hematology.

Research Interests: 

As a long term member and current principle investigator of the international collaborative group, the Leukemia and Lymphoma Molecular Profiling Project, Dr. Rimsza is involved with development of new molecular methods, including gene expression profiling in frozen and paraffin embedded tissues, for lymphoma diagnosis and prognosis. She also directs the Arizona Lymphoma Repository and collaborates with the biotech industry on new test development. Dr. Rimsza is currently the Chair of the Southwest Oncology Lymphoma Translational Medicine Subcommittee, working closely with the lymphoma physicians on new treatment strategies for patients.  Her primary research focuses on the biology of diffuse large B cell lymphoma, particularly the investigation of prognostic biomarkers and mechanisms of lost tumor immunosurveillance. She also has collaborative research projects in the field of neonatal thrombocytopenia.

Professional Service: 

Dr. Rimsza works as a diagnostic Hematopathologist, is the Director of Flow Cytometry, and the Directory of the Molecular Genetic Pathology Fellowship at the University Medical Center.
