Gund Postdoctoral Fellow, College of Agriculture and Life Sciences

Bryony's research integrates agroecology, entomology and veterinary parasitology and broadly seeks to understand the impacts of agricultural activities on insect biodiversity, ecosystem function and pest and parasite populations in livestock systems. Her work has focused on the environmental impacts of agricultural parasiticides on functionally important insect decomposer communities, and consideration of novel, environmentally sensitive approaches to parasite control. Her research aims to bring together farmers, vets and researchers to co-develop inclusive and socially relevant strategies for the future of food and farming.
With the Gund Institute and UVM Extension Bryony will be working on collaborative farmer-led projects to investigate the impacts of regenerative agricultural practices and Integrated Parasite Management (IPM) for livestock, on beneficial insect biodiversity, soil health, ecosystem function and pest and parasite regulation.
