Research Interests:

Biomaterials, biomedical devices, drug delivery

Novel and Potentially Multifunctional Chemotherapeutic Delivery Vehicles

Our research program is focused on the development of novel biomaterials and biomedical devices, with an emphasis on polyphosphate processing approaches that facilitate localized delivery of therapeutic agents, including anticancer drugs. Targeted applications include hepatocellular carcinoma (liver cancer), a challenging and often palliative condition for which chemotherapeutic agent delivery directly to the location of the tumor (and minimizing its impact on noncancerous cells) is being considered in conjunction with blocking of the tumor’s blood supply.
