  • Valorization of grape pomace, the common waste.Some published work here:
  • Development of Best Production Practices for Red Wines Over Time
  • Use of alternative techniques for the extraction of polyphenols from fruits and co-products. Some published work here: http://DOI: 10.1016/j.foodchem.2022.132703
  • Development of a physical method, tribology, to improve the understanding of red wine astringency perception.
  • Effect of viticultural and winemaking practices on tannins in red grapes and wines:
    • Effect of leaf removal on tannin content in grapes and wines.
    • Effect of nutrients spraying on vines and grape quality.
    • Effect of an Accentuated Cut Edges (ACE) and enzymes treatment on tannins and anthocyanins in Marquette wines. Some published work here:
    • Effect of fermentation of whole clusters. Some published work here:
    • Effect of Extended maceration, sulfur dioxide addition at bottling on red wine quality.
  • Interactions between cell wall polysaccharides and tannins in cold-hardy grapes
  • Alternative to cold stabilization
