Future Research

A broad goal of my laboratory is to utilize a systems approach to integrate the pathophysiology of a disease state with the known pharmacology of drugs to development optimal delivery systems for existing and novel therapies for cancer. We work to translate these findings from discovery and preclinical development to clinical use. Specifically, pharmacokinetic (PK) and pharmacodynamic (PD) principles are utilized as tools for the selection of novel therapeutic agents, design of rational drug delivery strategies to improve therapy, and elucidation of mechanisms underlying drug action. Passive and actively targeted drug delivery strategies, in particular nanoparticulate drug carriers (e.g., small, long-circulating liposomes), are engineered with maximal drug capacity and various release profiles to achieve optimal exposure at the target site, while limiting systemic toxicity by minimizing delivery to reactive non-target tissues. Currently we are developing lipid based nanoparticulates that exploit differences in tumor microenvironment (pH and enzyme expression/activity) to improve cancer chemotherapy.
