Graduate Research Topic
My work aims to improve enzymatic production of cellulases by to optimizing the fermentation conditions and substrate utilization for a given microorganism. This study uses wood extract produced during hot-water pretreatment as substrate to stimulate the enzymes yield. An increment in enzyme production would be a step in the right direction in the efforts to reduce the enzymatic cost and could help the biobased industry become more competitive.
Graduate Research Topic
My research is focused on production of Poly(lactic acid) from hemicellulosic wood sugars. PLA is a biodegradable and biocompatible polymer with the potential to replace petroleum derived plastics. Successful utilization of wood hemicellulosic sugars in the production of PLA would help in driving the biobased economy more favorable.

Graduate Research Topic
Polyhydroalkanoates (PHAs) are biopolyesters produced by many bacteria as carbon and energy storage compound under nutrient limiting conditions. PHAs have attracted a wide research interest because of their applications in biodegradable plastics and medical uses. Recent developments show that PHA and its related technologies are forming an industrial value chain ranging from fermentation, materials, energy to medical fields. Though compared with the petroleum products, the cost of PHA production is still expensive. One solution for this problem is using inexpensive renewable carbon sources, such as plant oils, molasses, starch, whey, wood extract and other industiral wastes to make PHAs production more economical. Another solution is to find a more enviornmental friendly and more economical method to purify the PHA from cell mass.
