I am trained in the research, application, assessment and implementation of the theory and practice of biological control of invasive agricultural and forest pests and weeds. My areas of expertise center on the evaluation of attributes of natural enemies as potential candidates for biological control of the invasive insect pests, hemlock woolly adelgid and elongate hemlock scale threatening the sustainability of eastern hemlock, Tsuga canadensis. My expertise is in the detailed study of the biology, behavior and field adaptation of biological control agents such as the Japanese coccinellid, Sasajiscymnus (=Pseudoscymnus) tsugae, and other predator species, and on the development of improved laboratory mass-rearing methods for them. I also conduct surveys and long-term field assessments of forest hemlock health to monitor the effects of biological control in the context of changing climatic and environmental conditions. I am the author and recipient of over 12 major federal grants from the USDA Forest Service and USDA APHIS for such research and employment over the past decade as a durational research entomologist with the CAES.

I have worked on numerous projects evaluating the potential of biological control agents, parasitoids and predators, for pests such as the chrysanthemum leaf-miner, hemlock woolly adelgid (HWA), elongate hemlock scale (EHS) and mile-a-minute weed (MAM). Many of the predator species originate from
I am continuing research into the evaluation of plant volatiles as potential attractants for improved field monitoring of Sasajiscymnus tsugae, a Japanese ladybeetle predator of HWA discovered by CAES; development of laboratory methods for culturing native predators of EHS for augmentative biological control, and continuation of the implementation and monitoring in Connecticut of the imported weevil, Rhinoncomimus latipes, for biological control of MAM.
