RESEARCH INTEREST
Wine Chemistry. Research interests are focused on the phenolic compounds isolated and purified from grape skins and seeds, the phenolic compounds found in grapes and wine and their biochemical and chemical changes during grape ripening, winemaking and aging. Example projects include understanding the relationship between astringency/bitterness and polyphenol compounds in red wine, aging potential in red wine and astringency intensity, grape harvest maturity and astringency intensity in grape berry.
