My research and teaching interests are in understanding the enological and viticultural parameters that shape wine flavor from vine to bottle. I am actively involved in the development of the Research and Teaching components of the new Enology and Viticulture program at Cornell.
The Sacks lab studies: Understanding effects of pre- and post-harvest factors on the organoleptic properties (flavor; color) of agricultural products, particularly wines and juices. Developing rapid and sensitive analytical techniques for measurement of flavor compounds.
Outreach and Extension Focus
Although I do not have a formal extension appointment, there is considerable overlap of my research and teaching interests with the practical problems of the statewide/regional wine and grape industries. I am a regular participant at winemaking workshops and industry technical conferences in New York State and elsewhere in the US.
I am currently Director of Undergraduate Studies and chair of the undergraduate teaching committee for the interdisciplinary enology and viticulture major (VIEN).
I also teach two courses as part of the VIEN major, cross-listed with Food Science (FDSC)
- Wines & Grapes: Analysis and Composition (FDSC 2400 / VIEN 2400, 3 cr) – intermediate-level undergraduate course on common and emerging analytical practices in the grape and wine industries
- Wine & Grape Flavor Chemistry (FDSC 4400 / VIEN 4400, 3 cr) – upper level course on flavor chemistry, primarily through the lens of wine
Finally, I oversee the undergraduate viticulture and enology Capstone Experience through VIEN 4000.
