Organic Pest Management Lab

Bio

The biggest impacts of my research has been in the areas of integration of livestock in apple production (4-5 farms have adopted this practice in the Upper Midwest) and improvement of the application and refinement of on-site and open rearing biological control systems in greenhouses (Numerous greenhouses in the Kalamazoo area have increased their use of these systems since my lab’s involvement).

Current assignment: Teaching 20% | Research 50% | Extension 30%

Program Description

Teaching

My current teaching program consists of a 3 credit advanced undergraduate/graduate course in organic pest management and serving as a research advisor/mentor to between 3-5 graduate students and 6-12 undergraduate students at a time. I have also regularly co-taught courses in sustainable agriculture and scientific writing.

Research

The overall goal of my program is to provide economically viable pest management knowledge, training and tactics for organic farming systems designed through a better understanding of agroecosystem dynamics, pest natural history, and behavior. Some of my ongoing research areas include: the identification of insect predators and their function in perennial agroecosystems, the elucidation of insect behavior as it pertains to response to pheromone dispensers and traps, the integration of animal and plant agricultural systems, optimization of “open rearing” biological control systems in protected culture agriculture and the impacts of tillage practices on weeds, insects, diseases, and nutrient cycling in perennial fruit systems.

Extension

My extension program is deeply integrated with my extension and teaching programs. At least 80% of my program’s research is on -farm, farmer participatory. I also maintain several webpages, regularly organize an organic fruit session at the GLEXPO and provide extension talks at meetings and trade shows. In 2014 I became the faculty coordinator of the Clarksville Research Center and have organized or helped put on 4 field days at the station in my first 6 months.
