Research Interests

My research is at the intersection of fluid mechanics, machine design and material science as applied to the forest bio-products industry.

Current Research Work

• High-value, energy-efficient mechanical pulp materials: This $4.5M proposal builds on three consecutive 5-year collaborative research programs led by the University of British Columbia (UBC) in the field of mechanical pulp and paper. These programs have fostered collaboration among mechanical pulp producers, electrical utilities, allied industries, and four Canadian universities. Past efforts have led to substantial outcomes, such as West Fraser Pulp’s $38 million investment to improve operations and the training of over 100 highly qualified personnel, many of whom have been retained by the industry. While previous programs focused primarily on energy reduction, the fourth phase of this program will expand into new, promising areas. These new areas, developed through extensive stakeholder consultation, will push the boundaries of mechanical pulping and introduce high-value applications. Specifically, the research will focus on improving system design for low-energy pulps, valorizing mechanical pulp fines, and developing novel products for sustainable packaging and absorbent materials.

• Modelling turbulent fibre suspensions: This research is aimed at developing a mathematical model of fibre orientation and concentration in turbulent fluids that can be implemented with conventional CFD techniques. The current approach is to develop an Eulerian formulation of fibre orientation and concentration that is computationally efficient and accounts for fibre-fibre and fibre-fluid interactions.
• Micro-Fibrillar Cellulose (MFC) development and application: Our research has shown that LC refining has been shown to be an low cost, energy efficient and industrially practical means of producing MFC materials. These LC refiner produced MFC have been used in a range of novel applications that include: paper strength additive, foam formed fibre material strength additive, micro-fibre reinforced polymer composites, etc.
