Christopher Williams is a professor of pharmacology and chair of the Division of Basic Pharmaceutical Sciences at Xavier’s University College of Pharmacy. As an undergraduate, he trained at Southern University in New Orleans, where he earned a Bachelor of Science in Biology. As a doctoral student at Tulane University, he pursued his Ph.D. in pharmacology while studying the impact of HIV-Tat protein on hematopoietic differentiation and chemokine receptor expression. As a postdoctoral fellow in the Tulane Cancer Center, he studied kinase and nuclear receptor signaling crosstalk in breast cancer progression and drug resistance. He later joined Xavier University College of Pharmacy as an assistant professor of pharmacology and has continued his work toward the development of novel therapeutic targets in breast cancer, with an emphasis on modulation of nuclear receptor signaling. His research focuses on discovering novel therapeutic approaches to the treatment of breast cancer.
