Emerald ash borer biological control
The invasive emerald ash borer has killed millions of ash trees in North America and continues to spread throughout the eastern United States and Canada. As a Postdoctoral Research Associate at Michigan State University (2009-2010), I worked with three parasitic wasp species (Oobius agrili, Tetrastichus planipennisi and Spathius agrili) introduced as biological control agents against emerald ash borer. Research priorities during this time included the development of a simple yet highly reliable and productive rearing method for T. planipennisi, the potential interactions between T. planipennisi and S. agrili at release sites, the suitability of different emerald ash borer larval stages for T. planipennisi rearing, and the development of a field-cage technique for evaluating climatic suitability for T. planipennisi and S. agrili.

Role of insects in promoting wood decomposition and forest productivity
Because dead wood is important in forest nutrient cycling, there is great interest in understanding what factors determine the rate by which it decomposes and the implications for forest productivity. Insects are assumed to contribute little to the process in most existing global decomposition models but this remains largely untested. As an Entomologist (2010-2014) with the Southern Research Station in Starkville, MS, I showed that up to a fifth of wood loss in southeastern US forests can be attributed to termites and other wood-feeding insects. I also have a study underway exploring the connection between wood-feeding insects and productivity in loblolly pine plantations and am investigating the effects of termites on fungal and bacterial communities.
