My research program studies the effects of agricultural management practices (tillage and cropping systems) on the nature and dynamics of soil organic matter (SOM).​

Guelph has the top Food Science program in the world. We do exciting research at the forefront of the Food Science endeavor.

We are interested in structure-function relationships of enzymes and enzyme evolution. We are studying steroid degrading enzymes from the pathogen Mycobacterium tuberculosis and other related bacteria. We are also interested in enzymes that can be used to detoxify environmental pollutants.

I am engaged in questions of applied landscape ecology in rural and agricultural landscapes, including changes in landscape patterns and the consequences of those changes on biodiversity, water quality, and culture.
