Academic Appointments

Professor of Biological Sciences
Associate Director, Institute of Arctic Studies
Chair Graduate Program in Ecology, Evolution, Ecosystems & Society

There are more than a million species of insects. A very few are notable pests that impact human welfare. What makes a pest? I study the population ecology of insects, especially forest pests. My lab group seeks to understand the forces that lead to high abundance and dramatic fluctuations in some species, and which stabilize the abundance of most species. Our research is basic, applied, usually collaborative, and sometimes interdisciplinary. My most important research colleagues are Dartmouth undergraduates, graduate students, and post-docs. Teaching at Dartmouth inspires my research and vice versa.
