The primary objective in my laboratory is to develop peptide- and peptidomimetic-pharmaceuticals for the treatment of dementia, cancer, and deficits in wound healing.  The common theme linking these disorders is dysfunction related to tissue remodeling. In dementia this dysfunction manifests as a lack of neuronal connectivity; in cancer it is exemplified by abnormal vascularization of the tumors and the ability of cancer cells to escape the primary tumor and metastasize to distance sites, and in deficient wound repair it is reflected in an inability of cells to invade the wound area. Interestingly the same regulatory proteins mediate the remodeling aspects of each of these disorders.

Our laboratory is interested in understanding the fundamental processes that underlie alterations in tissue structure and the growth factors that direct these processes. We are particularly interested in a family of enzymes called matrix metalloproteinases that regulate the dynamic composition of the extracellular matrix and the hepatocyte growth factor/ c-Met (its receptor) system, which is the premier regulator of cell migration. Based on these targets and using computer aided design and organic synthesis methodologies we have successfully generated molecules with potent cognitive enhancing activity, anti-cancer activity, and the ability to speed dermal wound repair. Our current work is focused on understanding the molecular mechanism of action of these putative drugs, designing new drug candidates with superior bioavailability characteristics, and identifying new therapeutic uses for these molecules.
