Current Research

For most materials, temperature is the most important environmental variable: properties like strength and electrical conductivity vary enormously depending on temperature. But in wood, moisture replaces temperature as the most important environmental variable. Moisture within the wood affects the mechanical properties of wood and can change physical properties such electrical conduction by as much as ten orders of magnitude (ten billion times). Many of the challenges of using wood as an engineering material (e.g. decay, corrosion of fasteners, and dimensional instability), arise from changes in the wood moisture content or an abundance of moisture within the wood.Wood-moisture relations have been studied since the 1950's, and have thus far been characterized empirically. Our research interests focus on developing a mechanistic understanding of wood-moisture relations so that more durable wood products can be created.


Research Interest

  • Electrical properties of wood
  • Corrosion of metal fasteners in wood
  • Fundamental research on wood-moisture relations
  • Microfluidics


Research Importance

Most "wood failures" are really "moisture failures".  Except in extreme events (earthquake, tornado, hurricane, etc.), wood fails in service because (1) it is attacked by mold, decay fungi, or other wood-degrading organisms or (2) it is weakened by splitting/checking caused by dimensional instability through moisture cycles- neither of which happen if the wood remains dry. The ultimate goal of my research is a transformative change in the way people understand how wood absorbs moisture, resulting in completely new methods of wood protection
