Atmospheric scientist (Air quality)

Current research and/or projects

C-PI  Sustainability metric projects: 1) Quantifying water use efficiency of crops 2) Regional methane emission estimates 3) Radiative forcing due to land use change 4) Mesoscale and turbulent transfer.

Research and/or project statements

As an expert in micrometeorology he developed techniques to quantify mass and energy exchange using tower and aircraft-based systems as well as techniques to quantify greenhouse gas emissions from point sources. He works with national and international teams in quantifying the role of the major terrestrial ecosystems on climate as well as the role of climate change on these ecosystems. He used aircraft-based flux measuring techniques to verify agriculture greenhouse gas inventory of methane and nitrous oxide at a regional scale. Some of my recent research is focused on improving estimates of the carbon footprint of agricultural products and helping Canadian farmers compete on the international markets. He co-edited and co-authored two books: “Health of our Air” and “Better Farming Better Air” which shed light on how efficient farming can improve air quality and reduce greenhouse gas emissions.
