Current Research:
   My research involves tree survival strategies and tree response to disturbance. Types of disturbance investigated includes storm injury, fire, changes in the soil environment, and human activity. Current work targets:

1) the relationship of tree-ring chemistry to internal biology and the external environment,

2) the relationship of dendrochronology to tree disease, human activities, and other environmental factors, and

3) the role of wood decay and compartmentalization following tree injury and infection for tree survival, forest competition, and element cycling.

Research and Development Applications: The current research is a foundation to develop tools to:

1) predict and control the effect on wood quality and tree health following tree injury from storms, fire, and human activity,

2) improve the prediction of tree growth from climatic and other environmental factors, and to

3) improve tree care in managed and urban forests.

Subject Area Index:   Acidic Deposition, Tree Physiology, Nutrient Cycling, Tree Biology, Tree Care, Forest Pathology.
