The viticulture and enology steering committee created a quarterly electronic newsletter, Appellation Cornell, to provide in-depth research articles written for laypersons, as well as faculty profiles, student profiles, industry profiles, and brief articles to highlight research, extension, and teaching activities of Cornell's Viticulture and Enology Program to a national and international audience. In its first year, readership comprised 1000 to 1500 online subscribers in 45 states, three Canadian provinces, Europe, Australia, and New Zealand. Fifty articles were published in 2010.

2010 to 2013

Environmental change affects all organisms either directly by physiological effects or indirectly by influencing the organisms with which they interact. My work investigates how ecological interactions are altered and how organisms evolve in response to these changes. The objective is to understand the trajectory and rate of these responses.

2009 to 2012

Powdery mildew is one of the world's most destructive diseases of grapevines. We know that infection of grapevines occurs as soon as they begin to grow in spring, but epidemics seem to stall for about six weeks and go nowhere fast. We've found that it's our cold nights that are suppressing the disease. Two modes of action are suggested. First, cold nights stimulate a temporary defense response in the youngest, and ordinarily most-susceptible, leaves. Second, cold causes direct damage to the mildew colonies.

2008 to 2011

The primary focus of this project is to support the existing and expanding grape and wine industries in New York and other states east of the Rocky Mountains by increasing the abilities of grape producers and their advisers to manage infectious diseases that limit profitability and preclude sustainable production if not addressed adequately. Additionally, the project has several components that are applicable to the grape industry in the western U.S. and to those in overseas locations.

2008 to 2011

Invasive plants change plant communities and ecosystem function across North America. My work assesses how changes in plant communities and management of invasive plants using biological control affects a wide range of native biota.


The objectives of this project are (1) to determine what species of Phytophthora are causing decline and death of European beech in northeast U.S. landscapes, (2) the geographic and host ranges of the respective pathogens, (3) determine why these diseases have become so prevalent in recent years, and (4) to develop reliable management strategies.


eClips is a digital database of 10,000 clips and more than 40 podcasts, focused on entrepreneurship, business, and leadership. The material is based on hundreds of in-depth interviews as well as business presentations. eClips makes it possible for business people (including small business owners and entrepreneurs), educators, and students to find targeted and focused information, because it is organized by entrepreneur, company, demographics, topics, and keywords.


Pollution of our water resources with sediment and absorbed chemicals caused by erosion remains an acute environmental problem. The ultimate goal of this project is to integrate all processes controlling erosion and sediment and pollutant transport from agricultural land to the nation`s water supplies.


It`s no surprise that severely diseased grapes make poor wine. However, we found that even trace levels of powdery mildew set in motion a sequence of events that results in severely downgraded and wine that could not be sold. The damage is not due to the powdery mildew itself, but to how it shifts the naturally occurring (and normally beneficial) microbial community on grape berries towards one that produces foul flavors and odors during winemaking.


This project has improved the turfgrass industry's understanding of the proper use of potassium fertilizers. This work has had to overcome more than 50 years of prejudice toward the use of potassium fertilizer, and only after several studies and practitioners demonstrating the value of reducing applications has the industry begun to shift away from gratuitous use.
