Research Interests

Developmental therapeutics of adult and pediatric cancers in both laboratory and clinical studies. Types of drugs studied include retinoids, "vitamin A derivatives" as tumor-selective differentiation or cytotoxic agents and drugs such as depletors of glutathione or Bcl-2 inhibitors that overcome resistance to traditional cytotoxic agents. Other research identifies molecular mechanisms of drug resistance that may provide novel therapeutic targets in childhood and adult cancers, development of novel preclinical testing models for childhood and adult cancer drug development, and clinical trials testing novel therapeutic approaches for cancer.
