Expertise:
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.

Education:
Ph.D. Wolfson College, University of Cambridge, England 1988
M. Phil. (Applied Entomology), Wolfson College, University of Cambridge
1984
B.A. (Hons.) Zoology, University of Oxford, England 1982

Station career:
Assistant Agricultural Scientist II 2003- present
Assistant Agricultural Scientist I 2000-2003
Postdoctoral Research Scientist 1994-2000

Past research:
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 Asia and I have experience working in the federal quarantine laboratory of the USDA Forest Service.  Extensive collaborations with Dr. Allen Cohen of North Carolina State University have resulted in the development of a novel and superior artificial dietary supplement for enhancing the survival and longevity of diverse predators imported for biological control of HWA and MAM.  Together with Dr. Cohen, we have also developed a series of process and production quality control tests for improving the laboratory rearing of predators for biological control of HWA.

Current research:
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.
