I lead the Building Moisture and Durability Research Team, one of four teams within the Durability and Wood Protection Research Work Unit at the Forest Products Laboratory. My work focuses on extending the service lives of buildings and wood products used in buildings by advancing a moisture performance based design approach and by promoting awareness of proper construction and operation practices. My primary research objectives include
- Durability of energy-efficient housing
- Building envelope performance
- Moisture management in buildings
- Heat, air, and moisture transfer
- Wood-moisture relations
- Hygrothermal properties of wood products
- Interior and exterior moisture loads
- Instrumentation for monitoring moisture levels in building assemblies
My doctoral research was conducted in the Department of Chemistry at the University of Wisconsin-Madison. I investigated how surfactant films at the gas-liquid interface control gas uptake and evaporation of water. These studies contributed to understanding the chemistry that occurs in sulfuric acid droplets in the upper troposphere and lower stratosphere.
Why This Research is Important
The sustainability and health of America’s forests depend on efficient use of our timber resources. Construction and repair of buildings account for approximately half of all lumber and other wood products (excluding paper) consumed annually in the U.S., and further increases in demand for residential and non-residential building products are anticipated. Increasing concerns about climate change, energy, and environmental impacts have stimulated a trend toward sustainable construction or “green” building. As a building material, wood has relatively low embodied energy and sequesters carbon over its service life. However, failure to properly manage moisture in buildings compromises service life and can lead to a host of undesirable consequences: mold growth, poor indoor air quality, corrosion of metals, loss of thermal resistance, damage from expansion or contraction, degradation by fungal decay or insects, and loss of strength possibly leading to structural failure. Research on moisture management in buildings is an essential aspect of sustainable forestry and green building.

As chair of the research subcommittee of ASHRAE Technical Committee (TC) 4.4 on Building Materials and Building Envelope Performance, I lead a group that is responsible for developing the TC's research program, shepherding new proposals through ASHRAE's review process, and monitoring on-going ASHRAE sponsored research. As a voting member of TC 4.4, I am involved in revising chapters for the ASHRAE Handbook of Fundamentals and the Handbook of HVAC Applications. I contribute to TC 1.12, Moisture Management in Buildings, through discussions on handbook chapters, research direction, and conference program sessions. In addition, I attend meetings of Standing Standard Project Committee (SSPC) 160, Criteria for Moisture-Control Design Analysis in Buildings.
