Current Research

My primary research goals are to develop: (1) low toxicity treatments for improved durability and performance of wood products(2) novel diagnostic methods to detect incipient decay, and (3) improved test methodologies for mold fungi. Integral to this work is an understanding of the mechanism of brown-rot decay so that treatments can be targeted to arrest growth of decay and mold fungi and sensitive detection methods can be designed based on fungal metabolites. Current research on wood protection systems utilizes synergistic combinations of organics and natural biocides to improve the durability of wood products. Accelerated test methods that rely on fungal metabolites, imaging technology, or field simulations are being developed for decay and mold detection in laboratory and field applications.

Research Interests

  • Development of low toxicity wood protection systems
  • Diagnostic methods for decay and mold fungi
  • Mechanism of brown-rot decay

Remediation of treated waste wood

Why This Research is Important

Wood as a sustainable and versatile building material and its increased use in construction minimizes life-cycle impacts of a structure while maximizing carbon storage for the life of the structure. Obviously, the longer the service life of that structure, the greater that benefit will be. Failure of wood in-service from biodeterioration by fungi and insects is a primary cause of user dissatisfaction. Chemical treatments can be used to improve wood’s resistance to fungal decay and insect damage, but new treatments are needed that are environmentally compatible and safe for indoor use and still prevent a multitude of organisms from attacking the wood over a long period of time. Innovative strategies to improve in-service durability include:

  • Bio-targets-targeted inhibition based on fungal or termite physiology
  • Synergistic multi-component biocides
  • Nano-biocides
  • Nano-carriers for controlled release of biocides
  • Naturally occurring plant extractives
  • Increased use of naturally durable underutilized or invasive wood species

Rapid methods are being developed for screening potential biocides in the laboratory and evaluating their performance in field tests to reduce the time it takes for new technologies to reach the market place.
