FDST 8070 - Food Proteins and Enzymes
Description of Research Interests
Our research seeks to understand the forces that govern protein structure and function with an emphasis on potential applications in food, biomaterials and medicine. Issues under investigation include enzyme catalysis, protein folding and aggregation, and engineering protein-based nanomaterials. This research involves a variety of biochemical, molecular biology and biophysical approaches and offers a training environment that blends basic and applied sciences to better understand and utilize food proteins and enzymes.
