The Cornell Dairy Fellows Program is designed for students who are interested in careers related to the dairy industry. Approximately 140 students participate in the Fellows Program each year. The program integrates a set of courses addressing the disciplines in the industry, industry and farm visits, in-depth farm analysis, seminars with industry leaders, industry conferences, exchange programs, international trips, and summer internships in dairy-related careers. These experiences allow students to apply their knowledge, skills, and mind-set in multiple real-life situations.


The goal of my research program is to identify and evaluate multiple strategies than can be integrated to control weeds in vegetable and fruit crops. The strategies may be traditional (chemical, mechanical) or more unusual (cover crops, natural products, weed biology/ecology, crop rotations). The intention is to develop methods of ensuring continued production of healthy foods while maintaining economic sustainability for growers and the safety of the food supply and environment.

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.


The primary objective of this program is to help farm managers improve the financial management of their businesses through the appropriate use of historical farm data and the application of modern farm business analysis techniques. The project identifies the business and financial information that fruit farmers need and provides a framework for use in identifying and evaluating the strengths and weaknesses of the farm business. In some instances, we provide cost and investment analysis estimates to help growers who are contemplating new enterprises (e.g., growing vinifera grapes).

2007 to 2016

Growers and consumers detest rotten onions. They cause financial losses to both groups. Most rots are caused by bacterial pathogens, and there are no good methods available to prevent the problem. If the losses from rot can be reduced or eliminated, everyone will be happier! In 2007, my program began to address bacterial disease problems of onions.


Selectable marker genes are widely used for the efficient transformation of crop plants. In most cases, selection is based on genes for antibiotic or herbicide resistance, which are most efficient. Due mainly to consumer and grower concerns, considerable effort has been put into developing strategies to eliminate marker genes from plants after transformation. However, these methods are generally of low efficiency.

2007 to 2009

Bacteria that cause vascular diseases in plants, including grapes, were discovered to migrate against the transpiration-induced flow of xylem sap using pilus-mediated twitching movements. Colonization of the vascular system by these bacteria was examined in vitro using nanofabricated microfluidic chambers in which the bacteria were discovered to auto-aggregate into cell masses that plugged the channels.


Oversight of the quality of nutrition education delivered through Cornell Cooperative Extension Associations is provided by this unit to ensure quality nutrition education and stewardship of funds.
