Biographical Narrative

Christopher Williams, Ph.D. is an assistant professor of pharmacology in the Department of Basic Pharmaceutical Sciences at Xavier. His current research focus is on understanding the underlying biological basis for resistance to SERMs, and development of orphan nuclear receptors as novel therapeutic targets in ER(-) breast cancer. Dr. Williams also collaborates with Dr. Brian Rowan at the Tulane Cancer Center in the study of health disparities in breast cancer, with an emphasis on therapeutic targeting of triple negative breast cancer in African American women.
