Primary Interests

Population Ecology and Biological Control of Invasive Forest Insects

Research Interests

Population dynamics of invasive forest insects with a current emphasis on winter moth, hemlock woolly adelgid and emerald ash borer. All three projects involve introduction, release and evaluation of natural enemies of these three invasive species as biological control agents. We are also making important contribution to the understanding of winter moth population ecology. It is famous species in Europe that has been subject of foundation research on insect population dynamics.  Earlier research on gypsy moth elucidated the role of small mammal predators and viral and fungal pathogens in the dynamics of gypsy moth populations. Other earlier work with browntail moth, another invasive defoliator from Europe that was widespread in the northeastern United States in the early 20th century, showed that it was driven to near extinction in most places by the introduced parasitoid  Compsilura concinnata. More recently my lab has taken a leading role in the application of DNA sequencing technology to a wide range of ecological problems.
