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 Sirex 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.
I am currently the vegetation scientist on site at Hubbard Brook Experimental Forest (HBEF) working as a team with Tim Fahey (Cornell University) and John Battles (UC Berkeley). Our charge is to quantify the plant community’s response to the press of chronic perturbations (e.g., warming climate, air pollution, invasive pest and diseases) and the pulse of catastrophic disturbances (e.g., ice storms, floods, windstorms); and to anticipate the consequences of these responses on the structure and function of the forest.
I am an ecologist in the field of Natural Resources, housed in the lab of Tim Fahey and Joe Yavitt. My main research interest on whole plant functionality and species interactions ranges from the individual level via plant communities to ecosystems. The majority of recent research projects focus on plant soil interactions and belowground carbon sequestration. The goal is to identify carbon dynamics, including contributing players of the soil system, specifically under extreme environmental conditions. I collaborate with colleagues at a local, regional, national and international level.
Alex Kudryavtsev conducts research and teaches online courses in environmental education. He focuses on urban environmental education, urban agriculture education, sense of place, green cities, and professional development of environmental educators around the world.
Through Dr. Li's research and outreach, she seeks to understand how networking among environmental educators in online learning communities and other platforms fosters innovation in their environmental education practice. She is currently teaching online courses and conducting research and international programs to bridge environmental education communities in China, the US and elsewhere. Yue Li Website
William (Bill) Siemer is a staff member in the Cornell Center for Social Sciences (CCSS). He conducts a range of research to better understand stakeholder attitudes, beliefs, and behaviors; support fish and wildlife management decisions; and advance integration of human and ecological dimensions of fish and wildlife management.
Kristi Sullivan's goal is to support practical approaches to conserving wildlife and biodiversity for future generations. Her research objectives are to develop practical methods for restoring habitat complexity and to determine effective means to sustain and conserve native wildlife in the face of environmental change.
I also oversee operations at the Arnot Research Sugarbush in the 4,200 acre Arnot Teaching and Research Forest in Van Etten, NY. This 6,000 tap maple operation serves as the primary research and education resource for the Cornell Maple Program.
