Risk and efficacy in biological control

I'm an entomologist and ecologist. I'm particularly interested in the the ecology of introduced insect populations.


I study parasitoids largely in the context of biological control.

Apparent competition

One area of interest is how host populations may interact indirectly through shared natural enemies.

Aphelinus certus

My dissertation work at the University of Minnesota centered on the aphid parasitoid Aphelinus certus, which was accidentally introduced into North America.

Perennial biomass

I am part of a collaborative group investigating the potential for perennial biomass plantings to improve biological control of soybean pests.
