Dr. Costanza has a B.A. in International Relations ad French from New York University, a M.Sc. in Forest Resources from the University of Maine and a Ph.D. in Forest Pathology, also from the University of Maine. The major focus of Dr. Costanza’s research pertains to tree response to stressors, both abiotic and biotic.
She is particularly interested in native pests and pathogens, and how changing environmental and climatic conditions can influence the frequency and severity of damage. Dr. Costanza frequently uses dendrochronology (tree-ring science) as a tool for assessing tree- and forest-level response to these stressors. Her research has led to numerous collaborative research projects with scientists, industry partners, and local community members.
