Andrew Horvai, MD, PhD

Research and Clinical Interests

My clinical activities include diagnostic surgical pathology (with special interest in bone and soft tissue pathology). My research focuses on the molecular pathogenesis of sarcomas as well as development of new diagnostic and prognostic tools in these rare tumors.
