Yiliang Cheng profile picture

Yiliang Cheng

PhD candidate (Spring 2024)

Yiliang is currently a Ph.D. student in Food Science and Human Nutrition (FSHN) at Iowa State University. She received her B.S degree in the Department of Food, Bioprocessing, and Nutrition Sciences at NC State University and M.S. degree in Food Science and Human Nutrition at ISU. Her research focuses on the effect of leaf removal treatment and winemaking practices on polyphenols from cold-hardy grapes and red wines. She has a strong interest in food biochemistry, and she is also excited for the opportunities to deeply learn about grape and wine chemistry.



Carter David

David Carter 

MS student (Fall 2024)

Carter is an MS student in Food Science and Technology at ISU. He received his B.S degree in Food Science here at ISU, and started to make his own wine at home before working in Dr. Watrelot’s lab as an undergraduate student. He started to work with the team to test for basic chemistry, phenolics, and tannins. Now as a master’s student, he is focused on different wine making techniques and different free sulfur dioxide additions that can affect the wine chemistry and the quality of wine made from cold hardy grape varieties grown in Iowa and other midwestern states.




Temporary Worker:

Alex pictureAlexander Gapinski

Alex is a temporary worker in the lab who graduated in Fall 2023 with a MS degree in Food Science and Technology at ISU. After receiving his BS in Food Science from the University of Minnesota, he spent some time studying wine through the Wine and Spirits Education Trust and the Wine Scholar Guild. He is excited to dive deeper into wine chemistry with a focus on characterizing cell wall material and tannins in cold-hardy hybrid grape varieties. The goal of Alex's research is to learn how these constituents interact and ultimately improve wine quality by maximizing extractable tannin.
