Research Summary:

Research interests are in the interdisciplinary areas of nutrition and cancer biology. Long term goals are to develop vitamin E analogs as anticancer agents, and to increase the understanding of the biological actions of vitamin E, both naturally occurring forms and synthetic analogs. Current investigations involve conducting chemotherapeutic studies with a vitamin E analog referred to as alpha-TEA, using syngeneic and xenograft preclinical animal models. Cell and molecular studies are focused on understanding signaling networks involved in alpha-TEA's pro-apoptotic and anti-survival mediated anti-cancer effects.
