My lab focuses on developing, implementing and monitoring biological control of invasive weed and insect pests. My research integrates contemporary ecological and evolutionary theory with the aim to increase the success and safety of biological control programs by better understanding how to collect, rear and release biological control agents to maximize their establishment success, population growth, and potential to adapt and spread in novel environments. Experimental approaches in the lab range from laboratory and greenhouse studies to large scale common garden and field experiments, and molecular methods.

I want students to succeed in my classes and enjoy the learning process. I promote and appreciate critical thinking and encourage students to speak up and actively engage in the class room. I thrive to present and discuss the latest research, novel concepts and ideas in ecology and evolution as they relate to biological control and invasive species management. I teach a course on biological control in odd spring semesters alternating in even years with a seminar course on eco-evolutionary dynamics in insect and plant populations.
Biological control is one of the only long-term solutions to problems with invasive species and crop pests, and thus it is crucial to understand the processes that lead to success or failure. We study the role of rapid evolutionary processes and reciprocal interactions between ecology and evolution in biological control agents and their targets. Research areas of particular interest include: the effects of hybridization on fitness, efficacy and host-specificity of biological control agents; the importance of genetic diversity and its interaction with demography in mediating agent and pest establishment and persistence; and the mechanisms that enable biological control agents and pests to adapt to novel environments.
I provide leadership in implementing new biological control programs across Michigan and expert advice to growers, natural area managers, landowners and the general public on best practices to release, redistribute and monitor agents.
