Horticulture & Human Health
Our research focus and efforts include both fundamental studies to understand the effects of production systems and environmental stresses on health-promoting antioxidants and secondary metabolites (phytochemicals) in food crops and applied studies to understand the effectiveness of gardening as a tool for health promotion or maintenance.
Fundamental studies use a wide range of approaches including those that aim at the molecular, cellular, and whole plant level. Studies are being conducted to develop strategies to use environmental stresses and biotechnology tools to augment health-promoting phytochemicals in fruits and vegetables.
