Professor, Department of Entomology Cornell AgriTech
I earned by PhD in Entomology at the University of California at Davis in 1989 where I studied insect ecology and pest management, including research on the effects on plant stress on herbivory and biological control. After postdoctoral positions at Stanford University and the University of California at Davis I came to the Department of Entomology at Cornell as an Assistant Professor in 1995, establishing a research and extension program at the New York State Agricultural Experiment Station in Geneva, NY (since renamed as Cornell AgriTech), with responsibilities for arthropod pests of grapes and small fruit crops. I also currently co-teach a course on Grape Pest Management. Outside of work I enjoy all manner of outdoor activities including cycling, hiking, backpacking, fly fishing, birding and cross-country skiing.
The overall goal of my research program is to understand the principal forces that influence the population dynamics and species interactions of herbivores in agricultural and natural ecosystems and use this information to devise and implement multi-tactic pest management programs. My areas of research expertise include plant-arthropod interactions, biological control, chemical ecology and integrated pest management. My more basic research is focused on how host plant traits and other environmental factors influence interactions between plants and their herbivores, and herbivores and natural enemies. My more applied research program focuses on the ecology and integrated control of specific arthropod pests of grapes and small fruit crops. My goal in extension is to translate and transfer results of applied research on pest biology and control to our grower clientele so that they will be better informed and better able to make sound pest management decisions. Educating growers and pest control advisors as to the proper and effective use of pesticides is an important aspect of my responsibilities. In addition, however, I include other approaches to pest control such as the use of predators and parasites, manipulation of pest behavior, cultural techniques and host plant resistance.
