Biography

Dr. Flaherty completed her PhD at the University of New Brunswick, examining novel tri-trophic interactions between an exotic wood borer and its host tree, competitors and natural enemies in an introduced habitat in Nova Scotia. Her post-doctoral work at the University of Massachusetts examined biological control of the hemlock woolly adelgid by an established predatory beetle. Dr. Flaherty's current research focuses on the population dynamics of the forest tent caterpillar, improving trapping methodologies for early detection of invasive forest insects and examining the impact of an invasive weed (garlic mustard) on belowground invertebrate communities.
