Clinical Interests

Dr. Druley is interested in the mechanisms of abnormal childhood development that cause a predisposition to childhood cancer. From this interest, he is the co-director of the Pediatric Cancer Predisposition Program (http://www.stlouischildrens.org/our-services/cancer-predisposition-program), which is a multi-disciplinary effort to provide longitudinal surveillance or treatment to children with an increased risk of cancer and study how abnormal development leads to pediatric cancer.
