Primary Interests

Dr. Clouston has been working in the field of timber engineering for over 30 years. Author on over than 80 publications, she conducts research on the structural behavior and efficient use of advanced bio-based (wood, grass and straw) composite materials. Current research topics include CLT panels from low-value eastern species, timber-concrete composite floor systems, and laminated veneer bamboo connections. She teaches courses in structural timber design, bio-based composites and material mechanics/tectonics to architects, engineers, and building technologists.

Dr. Clouston is a registered professional engineer (EGBC) and serves as Associate Editor of the ASCE Journal of Materials in Civil Engineering. In 2016, she led the design, engineering, and construction of a large student design/build project that culminated in the construction of a Massive Timber Dome (30ft x 30ft) on the plaza of the UMass Fine Arts Center.
