Faculty
Research Interests: 
My research interests are focused on efforts that improve seafood/muscle food quality and safety. Particularly with regard to understanding how injection/marinade and high pressure processes can be used to enhance fresh product quality while minimizing impacts on nutritional value and safety. Interests also center on enhancing utilization of co-products generated from seafood processing and minimization of processing waste.
