Research Interests:

• Ecology of bark beetles (Scolytidae). Field studies on the population ecology of bark beetles and associated organisms.
• Conifer defense mechanisms. Studies of the defense systems of conifers against bark beetles and pathogens.
• Theoretical Ecology. Contributions to a general theory of population dynamics, pest outbreaks, and food web interactions.

Education:

• B.Sc. 1959 Imperial College of Science and Technology, London
• M.S. 1961 University of California, Berkeley
