Research Associate

I’ve worked with a variety of taxonomic groups (reptiles, insects, fungi, nematodes) on population-level ecology and evolution questions. I particularly enjoy using molecular genetic markers to gain insight into questions about dispersal, hybridization, invasive species, and symbiotic relationships. Complex interrelationships of native and introduced insects, their pathogens, symbionts, and predators have been my focus at Cornell since 2014. I’ve enjoyed investigating <i>Sirex</i> woodwasp, gypsy moth, and hemlock woolly adelgid (HWA). My current focus as Research Associate in the New York State Hemlock Initiative is on a pair of closely-related species of predatory flies from western North America, introduced as potential biological control agents against HWA.<br><br>
