Research Interests

My students and I conduct inter-disciplinary research in the fields of geomatics, physical hydrology and the biogeosciences.  The overarching goal of our efforts is to improve scientific understanding of ecosystem processes and change in Canadian landscapes.   My PhD research focussed on watershed hydrology and mercury sensitivity in Precambrian Shield regions of Ontario, making extensive use high-resolution digital terrain analysis with airborne Light Detection and Ranging (LiDAR).  I continue to work on similar topics and have also developed additional research interests and projects in the areas of northern peatland hydrology and geomorphology, stream health assessment in agricultural landscapes, mercury cycling in Precambrian Shield lakes, and remote predictive mapping of surficial geological materials throughout northern Canada.  I work closely with government, industry and not-for-profit partners and welcome new research opportunities that fall within my areas of interest.
