Current Research

My main research areas are human impacts on the geochemical cycles of potentially toxic trace elements, including archives of atmospheric change (peat bogs and polar ice cores), fate in soils and sediments, and impacts on natural freshwaters. Read more ...

Two

The SWAMP lab is concerned with environmental quality in its broadest sense: the quality of our soil resources, the water we drink, the air we breathe, and the food we eat. The research lab is a unique state-of-the-art, metal-free, clean-lab and analytical facility. Read more ...

Three

I am the President of the Elmvale Foundation, a Canadian, federally registered charity for environmental science education which I created in 2007. The main public education initiative of this Foundation is the Elmvale Water Festival which uses the water emanating from artesian springs in the Elmvale area as a tool for environmental education.
