Expertise

My primary research focus is in the area of food physical chemistry. Chemical reactions occurring in foods over time cause the products to become less acceptable to consumers. Studies in my lab involve understanding the variables that impact food chemical stability so that shelf life can be optimized. For example, we evaluated the role of buffer type, concentration, and pH on the loss of thiamin (a vitamin), tagatose (a prebiotic), and rebaudioside A (a sweetener).
