Teaching Responsibilities

• FOR 5494 Natural Resource Research Procedures

Selected Research Activities

• Evaluation of the changes in soil carbon sequestration in the soils of deciduous forest stands as influenced by time and site factors.
• Use of minimalist quantitative mechanistic models to describe and predict nutrient uptake by woody species. Current focus is on loblolly pine.
