    Research synopsis

    My research interests include targeted drug delivery, developmental cancer therapeutics and therapeutic peptides and proteins. My background and training included the development of stimulus-responsive drug carriers for targeting drugs to solid tumors. We utilized a thermally responsive carrier to target therapeutic peptides and small molecule chemotherapeutics to tumor sites using focused heating. My current research interests include developing novel nanoparticle platforms for delivery of peptide, protein and siRNA – based therapeutics.

    Peptides and siRNA have great potential as therapeutic agents due to their ease of design and high specificity for their targets. However, their usefulness as drugs is limited by their poor performance in the body, including rapid degradation and poor tumor penetration. We are working to develop carriers for peptide and siRNA drugs that can overcome these limitations and make these agents effective for cancer therapy.

    We are also interested in drug delivery during pregnancy. We are developing carriers that can be fused to therapeutic agents, including chemotherapeutics and peptides, that prevent them from crossing the placenta and reaching the baby. Our goal is to develop a means to treat disorders of pregnancy (such as preeclampsia), or to deliver cancer chemotherapy, to pregnant patients without risking harm to the developing fetus from drug exposure.
