I received my B.S. in Biology from Calvin College in Grand Rapids, MI in 1997 and my M.S. in Biological Sciences from Eastern Illinois University in Charleston, IL in 2000. My Master's research was on the emergence and reproductive behaviors of the Japanese beetle. I studied when male and female beetles emerged from the soil and how emergence related to specific mating and egg laying behaviors.

As a research technician in the Berry Crops Entomology laboratory, I am involved in various projects with a primary focus on two important pests, the spotted wing Drosophila and blueberry stem gall wasp.  

In our spare time, my wife and I enjoy doing just about anything outside. This includes everything from cross-country skiing in winter to running all year round. We also try to keep up with our two daughters who always keep us busy!
