Dr. Hayes Dixon is a pediatric surgeon and a leading scientist with focus on the treatment of desmoplastic small round cell tumors (DSRCT), a rare sarcoma, which spreads throughout the abdominal and chest cavity. She was the first surgeon to perform cytoreductive surgery and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in a pediatric patient, improving the survival from 30% to 60% based on complete removal of 100s of intra-abdominal tumor implants and HIPEC. Ever since, Dr. Hayes Dixon has treated patients from across the globe and traveled extensively in the U.S. and abroad, teaching the operation to other surgeons.

Dr. Hayes Dixon is the first African American female pediatric surgeon board-certified in the United States, the first female Dean of the College of Medicine at Howard university and the first female Chief of Surgery for Howard University Department of Surgery.

Dr. Hayes Dixon has had a basic science research lab since the beginning of her career. In her lab she has developed novel orthotopic xenograft models. The most current one is of Desmoplastic Small Round Cell Tumor. It is within this model that she has been able to show using single cells, sequencing, and other methods that androgen receptor is the primary driver of the growth and metastasis of desmoplastic small round cell tumor.

Currently Dr. Hayes Dixon is the Dean of Howard University College of Medicine, where she also served as the Chair of the Department of Surgery. Prior to joining Howard University, Dr. Hayes Dixon served as the Surgeon-in-Chief and Division Chief of Pediatric Surgery at the University of North Carolina (UNC) Children’s Hospital, where she also served as a Faculty Member here at UNC Surgery with roles of Professor of Pediatric Surgery and Surgical Oncology. Before UNC she was the Section Chief of Pediatric Surgery at the University of Texas (UT) MD Anderson Cancer Center.
