Primary Interests

Population dynamics of invasive forest insects with a current emphasis on winter moth and hemlock woolly adelgid. Both projects involve introduction, release and evaluation of natural enemies of these two species as biological control agents. Earlier research on gypsy moth elucidated the role of small mammal predators and viral and fungal pathogens in the dynamics of gypsy moth populations.

Courses Taught

  • Insects and pathogens of forests and shade trees – 3 credits, alternate years
  • Introductory ecology. (in Biology dept.) – 3 credits, each spring
  • Readings in population and community ecology – 1 credit Fall 2012
