About Me

I am an environmental chemist who began my career by studying the mass balance of contaminants, specifically mercury, in the St. Lawrence River basin. I then worked for the Canadian Forces as an occupational hygienist, where I did some work on noise in Sea King helicopters, but mainly on soldiers' exposure to atmospheric emissions produced during live gun firing.

Since arriving at the University of Alberta, I have been developing a program on nanoparticles and ultrafine particles. Specifically, I am interested in developing techniques for sampling and analyzing nanoparticles and ultrafine particles and assessing the health effects of these particles. 

I am a member of the Alberta Respiratory Centre.

My program presently concentrates on exposure assessment to welding fumes and their health effects using urinary metabolite profiling. My group has completed a research project on urinary metabolites in welder apprentices and we are now looking at using metals in exhaled breath condensates of welders as a biomarker of exposure to welding fumes.
