I investigate how chemical ecology drives the process of plant domestication and the development of agricultural systems.  Informally, I inquire "what do people want from their crops and how do they get it?"  This curiosity spans a wide variety of research questions including ethnobotanical, biochemical, genetic, and agroecological approaches to understanding the complex ecology that exists between plants, predators, and humans in the agricultural system.

            Specifically, my recent research projects have focused on domestication and crop toxicity, specializing in two traditional crops native to South America that have retained toxicity in the domesticated form: “oca” (Oxalis tuberosa Molina) and “manioc” (Manihot esculenta Crantz). Both crops display an interesting syndrome of domestication whereby both toxic and non-toxic varieties are maintained, each with unique cultural customs of food preparation.  These crops provide a new research model to address the conflicting anthropogenic and ecosystemic selective pressures present in agricultural systems.
