    Research Interests
    Dr. Stephen Howell’s work focuses on the development of novel drugs and drug delivery systems for the treatment of cancer, and on the molecular and genetic mechanisms underlying the development of drug resistance.  He conducted much of the early pharmacokinetic information and clinical trials work on intraperitoneal chemotherapy for the treatment of ovarian cancer.  His laboratory has contributed importantly to the current understanding of how the platinum-containing drugs enter, traffic through and exit from ovarian cancer cells, and how much cells become resistant to these drugs.
