Clinical Interests

Dr. Cooper received her MD and PhD training at The Ohio State University in Columbus, Ohio. Her PhD work focused on understanding the biology of a subset of human immune cells known as “natural killer” or NK cells. After graduating from medical school she moved to St. Louis and completed her residency and fellowship training at St. Louis Children’s Hospital and Washington University. Dr. Cooper has a clinical interest in primary disorders of the immune system and sees patients in the rheumatology and immunology clinics. She is the Director of the Clinical Immunology program and the Jeffrey Modell Diagnostic and Research Center for Primary Immunodeficiencies at St. Louis Children's Hospital.
