Research: 

Current research interests include: the structure-function relationships of food and non-food related enzymes using molecular biology and various physico-chemical techniques (eg. circular dichroism spectroscopy, micro-calorimeter, small angle neutron scattering, ultracentrifugation, enzyme kinetics, etc.), carbohydrate metabolism in potatoes as it related to process quality as well as various applications of food-related nanoscale science and technology.
