My research program is centered on climatology, specifically relationships between North American drought variability and broad-scale ocean-atmosphere variability. My recent research includes an analysis of the role of land-falling tropical cyclones in ameliorating drought conditions throughout the Southeast, and an analysis of the influence of North Atlantic climate variability on historic changes in tupelo honey production in the Florida panhandle inferred from tree ring data.
