How does this work?

For over 25 years, I have been dedicated to early stage research and discovery of nutritional technologies. I directed scientific teams across the globe creating the next generation of pediatric and adult products that advance early life development, promote healthy aging, support gut health, and optimize cognitive development. My scientific passion and interest revolves around dietary fiber and the gut microbiome. My research resulted in the creation and commercial launch of novel fiber blends in medical nutrition products and the introduction of slowly digested carbohydrates into products for people with diabetes. I also led a research and ingredients development program that resulted in the first commercial launch of human milk oligosaccharides in infant formula. I am a strong proponent of Academic/Private Industry partnerships and established the Center for Nutrition, Learning and Memory, a research partnership between Abbott and the University of Illinois, focused on studying the effects of nutrition on cognitive performance.
