My general area of interest is the ecology of trees and forests.
Specific Goal: To study the effects of natural and human-causes stresses on tree growth and mortality. Most recently, to study how variation in climate variables influences growth of trees and whether there are patterns of similar responses among tree species that share anatomical, ecological, and taxonomic characteristics.
In our research we use precise measurement of annual growth tree-rings to evaluate growth responses to variation in specific climate variables, including monthly and seasonal temperature, precipitation, drought indices, and modeled evapotranspiration. Core samples from trees allow for measurement of annual tree-ring width over periods of decades to centuries while causing minimal damage to living trees. Tree-ring data from up to 30 trees per site and from up to 360 sites distributed across eastern North America have been used to document the growth responses of oak species to climate variation. Current research has focused on expanding these analyses to other tree species in this region with the goal of looking for differences and commonalities among species.
