Professor of Environmental Conservation
1979, Ph.D. University of California at Berkeley
My laboratory conducts research on population dynamics and biological control of invasive forest insects. His early work focused on gypsy moth and the impact of small mammal predators and viral and fungal pathogens on that system. More recent projects focus on the population dynamics of browntail moth, hemlock woolly adelgid, and winter moth. He is currently involved with efforts to introduce predatory beetles to control hemlock woolly adelgid and a tachinid parasitoid to control winter moth.
