Dr. Hart's research interest was forest insects in urban and woody biomass plantation systems, including agroforestry. His specific interests are in determining the impact of economic species and in the plant-insect interface, particularly in the mechanisms responsible for resistance to attack. Other research was in the study of within-plantation dispersal and the definition and conservation of natural enemy complexes. Dr. Hart's research was done in cooperation with personnel from the departments of Forestry and Plant Pathology. Dr. Hart retired in January 2002.
