Education and Background (full CV)
Ph.D. Zoology. University of Wisconsin-Madison. Thesis title: “Do bees matter to cranberry? The effect of bees, landscape, and local management on cranberry yield”. December 2013. Advisor: Dr. Claudio Gratton.
M.S. Entomology and Agroecology. University of Wisconsin-Madison. Thesis Title: “Conservation of Non-Crop Habitats and Ecosystem Services in Wisconsin Potatoes.” May 2009. Advisor: Dr. Caludio Gratton.
B.A. Environmental Studies, with Honors. Bates College, Lewiston, ME. Thesis Title: “Impact of Patch Retention on Ground Beetle Communities in Western Maine.” May 2003. Advisor: Dr. Curtis Bohlen.
I am interested in how local and landscape characteristics influence pollinators in agro-ecosystems. Most recently my research has focused on how the landscape surrounding commercial apiaries influences honey bee hive success.
