RESEARCH

My research interests are mainly on extractives of wood and their bioactivities, natural durability of wood, wood chemistry, wood preservation, photodegradation and photostabilization of wood and coatings, surface modification of wood. Research approaches of this lab focus on phytochemical analyses and biological screenings of species indigenous to Taiwan. The biological screenings include anti-bacteria, anti-termites, anti-mites, anti-mildew, anti-mosquito larvae, anti-fungi, antioxidant, and anti-inflammation effects. Additionally, developing various reagents for protecting the green color of bamboo culms is very imperative for the bamboo industry.
