• Research Focus Area: Health Disparities, Treatment, Informatics, Detection, Carcinogenesis, Diagnosis/ Prognosis
• Type of Research: Basic
• Research Interest Statement: Integrating datamining, modeling and experimental approaches to develop safer targeted cancer therapeutics Recent advances in targeted cancer therapeutics boast superior health outcomes relative to traditional chemotherapy drugs; however, hepatotoxicity poses a major clinical concern for patients undergoing treatment with these revolutionary drugs. Drug metabolism plays a central role in toxicological mechanisms and thus, my research focuses on assessing clearance and bioactivation of drugs and subsequent biological, pharmacological and toxicological impacts on human health. In practice, my group integrates and leverages powerful analytical, biochemical, and computational tools to identify and quantitate small molecules including drugs present in biological samples and generated from metabolic reactions. Next, we correlate findings to biological activity and in vivo outcomes such as liver toxicity to establish toxicological mechanisms and the factors impacting those outcomes. Knowledge gained from these studies will aid in the design and use of safer targeted cancer therapeutics by minimizing associated toxicities that limit their use in the clinic.
