Current Research

Of primary interest is to understand seasonal and long-term ecophysiological relationships among above-ground (i.e., photosynthesis, canopy light) and root/soil attributes (i.e., plant available water, seasonal root carbohydrate relations) that regulate loblolly and longleaf pine production. Crown physiology, leaf area dynamics, root production and distribution, and tree growth are studied in response to stand environment and silvicultural practices to determine how environmental variables such as prolonged drought and management tools such as prescribed fire control soil resource availability, carbon fixation and allocation, and forest sustainability.
