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.

Research Interests
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.
Personal Interests
Baking, sewing, knitting, gardening, cycling, skiing, curling, hunting.
