Over the past 10 years, Dr. Foley has had the opportunity to work with some of the world's most invasive plants and animals. His research has focused on invasion ecology from a global change perspective, aiming to understand how native and non-native biological organisms influence invasive pest populations in both terrestrial and aquatic ecosystems. Dr. Foley employs a combination of modeling, field surveys, molecular biology, bench-top analytical tools, and field experiments to address various theoretical and applied concepts of invasion ecology.

Station Career:

Assistant Agricultural Scientist II: 2023-present


Past Research:

Dr. Foley earned his Ph.D. in the Department of Entomology at Virginia Tech working with Dr. Scott Salom, the forest and biological control specialist. His doctorial research was focused on the post-release mass-production, distribution, and establishment of biological control agents for the highly invasive hemlock woolly adelgid. Dr. Foley has worked with local, state, and federal land managers throughout hemlock’s infested range to understand and assist in integrating biological control agents within a large management strategy. Prior to arriving at Virginia Tech, Dr. Foley earned his masters at the University of Florida and Bachelors degree at Florida Atlantic University while simultaneously working for the USDA Invasive Plant Research Lab. During his masters, he studied the symbiotic relationship of nematodes associated with invasive subterranean termites. While working as a technician, Dr. Foley was intricate in the pre- and post-release evaluations of several biological control agents for some of south Florida’s most invasive aquatic plant species.  


Current Research:

Dr. Foley’s current research is centered on the impacts and management of invasive aquatic species throughout Connecticut, with a particular focus on a new strain of Hydrilla in the Connecticut River. Hydrilla is an invasive aquatic plant that can quickly dominate waterways, outcompeting native species and causing significant environmental damage. The new strain of Hydrilla is of particular concern as it has been found to be more aggressive and resilient than previous strains, making it more difficult to control. Dr. Foley's research is aimed at understanding the potential impacts of this new strain of Hydrilla on the Connecticut River and developing effective management strategies to mitigate its negative effects. Through his work, he is investigating a range of management techniques, including herbicides, mechanical harvesting, and biological control agents to help control the spread of Hydrilla and prevent its establishment in other waterways. Dr. Foley's research is essential for protecting the ecological integrity of the Connecticut River and ensuring the sustainability of the region's aquatic ecosystems.
