RESEARCH AND EXTENSION GRANT REVIEW PANELS

NYS IPM grants program, Chair of Executive Committee (research and extension)

Western Regional IPM Grants Program – 2005

As a professor of entomology my goal is advance the integrated pest management (IPM) strategy through mission-oriented research and extension. My research program is directed at improving our understanding of pest biology and ecology in vegetable crop systems and applying that information to develop practical, cost-effective, and environmentally sensitive pest management tactics. The goal of my extension program is to ensure that new knowledge is delivered to the end-user and adapted to their needs. As Director of the NYS IPM Program my goal was to help advance IPM in both the agricultural and non-agricultural sectors. To make this happen, I along with program staff, engage a wide audience of stakeholders to make sure that we are accountable and effectively accomplishing our mission. To help the program grow I pursue all funding opportunities including those through New York State, foundations, and competitive grants. To enhance coordination of IPM efforts across states I have taken a lead role in the regional IPM efforts and actively contribute to IPM discussions at the national level. As Associate Director of Cornell Cooperative Extension for Agriculture and Food Systems I helped enhance connectivity among extension staff and programming on campus and in the counties and act as liaison with agricultural and related industries and organizations. Now as the Director of the CUAES, I oversee the allocation of Federal Formula Fund funding, respond to the needs of applied research and extension, and act as liaison to several to agencies and the colleges of Human Ecology and Veterinary Medicine. As Associate Dean, I serve as a member of the leadership team of the College of Agriculture and Life Sciences, contribute to strategic planning; help to determine the allocation of resource for college programs; represent the college to college and university groups; provide advice on diverse college initiatives; and oversee coordination of farm and greenhouse/growth chamber facilities and personnel.
