Trees and shrubs in urban landscapes provide many services for people and the environment. Research and Extension efforts in my lab also focus on insect ecology and arboriculture in urban environments.
We are particularly interested in how features of urban landscapes like heat, drought, and surrounding vegetation affect urban trees and the insects that live and feed on them. Our ultimate goal is to develop more sustainable strategies for urban tree selection and insect pest management.
