As part of the Developmental Therapeutics/GI Laboratory at UCD, my research is focused on pre-clinical studies of novel, rationally-based drugs for the treatment of advanced colorectal cancer, utilizing both cell culture and in vivo mouse model systems. These studies serve as a basis for therapeutic treatment options/choices for patients with advanced GI cancers in the UC Phase I Clinical Trials Program.
