Contact Robert H. Falk
Dr. Falk's research currently focuses on the development of value-added products from wood waste materials. This work includes the development of reuse options for salvaged lumber and timber as well as the development of composites from waste natural fibers and waste thermoplastics. In addition to developing a basic understanding of the engineering properties of these materials, Dr. Falk is active in helping develop the engineering property and engineering design standards necessary to facilitate their widespread use in construction applications.
