His area of expertise is in the application of advanced, next-generation chemistry to solve various long-standing technological problems in the pulp and paper industry. He has pioneered the work in the novel modification of lignin functional groups, the development of fibre-reactive radical scavengers for the photostabilization of lignocellulosic materials, and the bleaching of lignin-rich wood pulps with phosphorus-based chemicals. He has developed a number of novel processes for the bleaching and brightness stabilization of lignin-rich wood pulps. He has over 70 publications including one edited book on Chemical Modification, Properties and Usage of Lignin, five issued international patents and several pending US and Canadian patents. He has won a number of prestigious awards including the 2004 Journal of Pulp and Paper Science Best Paper Award and the 2005 Pulp and Paper Technical Association of Canada Douglas Atack Award for Best Mechanical Pulping Paper.
