I have more than 25 years of experience in Mineral and Coal Processing Engineering working with industry, academia, and government. My first position was at the University of Alberta, followed by the Alberta Research Council. In the 1990s I held a senior Licensed Scientist positon at the British Columbia Ministry of Energy in Victoria, B.C., and I was engaged in consulting work for the mining industry before I decided to pursue my PhD studies at UBC. After completing my PhD degree in 2006, I moved to Australia to work at the Julius Kruttschnitt Mineral Research Centre, the center of excellence for mineral processing at the University of Queensland. In 2011, I returned to work for the industry as a Senior Research Engineer at Teck Resources until I joined the UBC Mining Engineering department as Assistant Professor in 2014.

In 2015, together with prof. Veiga we founded a new center dedicated to research in the area of waste re-processing, which has been financially supported by the Dean of Applied Sciences. Since establishing the center, we have attracted local recycling companies to collaborate with us on the recovery of valuable metals from what are otherwise municipal waste streams.

My interests are also in in the area of minerals and coal characterization. I carry out this type of research to advance Mineral Processing technologies. My major accomplishment in this field is my work carried out on the washability (ease of cleaning) of coal. I examined the washability characteristics of British Columbia coals in relation to the lithology of the seam, and established a washability parameter that can be related to the inherent coal characteristics. This allow geologists to predict the quality of coal in terms of washability. I published a manuscript-type paper (solo authorship) on the topic for the BC Ministry of Energy and Mines in 1994. In the field of Mineral Processing, I carried out work on the implementation of the Floatability Index into the JKSimFloat flotation model while working at Julius Kruttshnitt Mineral Research Centre (JKMRC-Australia). This resulted in number of scientific papers on the characterization of the hydrophobicity of minerals, as evidenced in the publications list.

I am is also actively participating in the current coal carbonization (coal pyrolysis and coke-making processes) research by taking part in the Canadian Coal Carbonization Research Association group activities, providing advice in seminars and private consultations with the industry. I have been involved in research with members of CERC (Clean Energy Centre-UBC) on developing fuels that combine biomass with coal fines. I co-supervise graduate students in the Chemical Biological Engineering department involved in this research area.
