PROFILE

My research explores the ecology and management of native and exotic forest insect pests, including semiochemistry, host and mate finding behaviour, community and population ecology. I am interested in using empirical and theoretical approaches to understand the factors involved in pushing forest insect populations over the edge, causing them to transition from endemic to epidemic states.
