Research Interests

Food Chemistry and Biochemistry, particularly in subject areas of enzymology and phytochemistry; Specific interests include: 1) identification, characterization and enrichment of health-promoting, bioactive compounds in foods, 2) effect of processing on bioactive compounds and other quality attributes in vegetables, fruits and grains, 3) characterization of enzymes in foods and as processing aides, 4) organosulfur chemistry in Alliums and related species.

Current projects include: Processing of Allium tissue to enrich retention of bioactive organosulfur compounds, Biofortification of vegetables in organoselenium compounds for cancer chemopreventive benefits, Identification of cancer chemopreventive agents from soybean, maize and other vegetables, Processing of vegetables for enhanced quality.
