I study the ecological interactions between plants, herbivores, and carnivores in wild and agricultural Solanaceous plant species. My approach focuses on understanding behavioral and phytochemical mechanisms of such tri-trophic interactions, testing theory on the organization of multi-trophic communities, and generating novel strategies to control insect pests.

I teach a variety of courses at Cornell including: BioEE 3690/ENTOM 3690/BioNB 3690 Chemical Ecology, BioEE 4550/ENTOM 4550 Insect Ecology, and BioEE 1610 Ecology and the Environment.

My research goals are to develop a predictive framework for understanding the complex interactions that occur between plant and insect species. Studies of fundamental ecological processes, in both agricultural and wild systems, can provide insight into controlling insect pests and understanding the natural world. My research focuses on ecological interactions between plants, herbivores, and carnivores in agricultural and wild Solanaceous plants. Current research projects focus on understanding the non-consumptive effects of predators on prey and understanding how plants integrate their defenses against multiple attackers.
