Dr. Yanyan Li

Assistant Professor in Food Science and Human Nutrition (Nutritional Biochemistry)

Degree: Ph.D. 2011, Ohio State University
Phone: 207-581-3134
Location: 113 Hitchner Hall

Professional/Research Interests:
The goal of my research program is to understand the health benefits of bioactive dietary components, in particular anti-cancer and anti-inflammatory properties and the molecular mechanisms. Earlier in my career, my work revealed novel mechanisms of sulforaphane (a bioactive isothiocyanate from broccoli/broccoli sprouts) for cancer chemoprevention, including the inhibition of Hsp90 function and targeting of a cancer stem cell self-renewal pathway. Since 2016 I have been studying the protective role of different broccoli sprout diets in colon inflammation and inflammation-associated tumorigenesis, as well as the interplay between bioactives and gut microbiota, which has become the primary focus of my current research.
