Research Interests
I am interested in how local and landscape characteristics influence beneficial insect communities in agroecosystems. More specifically, I study how farm management practices and habitat availability influence pollinators and pollination.
Personal Interests
Baking, sewing, knitting, gardening, cycling, skiing, curling, hunting.
