Welcome
Here is a synopsis of my teaching,
conservation activities, and research programme. My studies focus
primarily on the spatial ecology, demography, and conservation of terrestrial
mammals in the North. Much of my recent efforts concern woodland caribou,
the shy and secretive animals that live year-round in the taiga.
My research is also centred on issues of spatial and temporal scaling −
how ecological conclusions depend on the window size on the world.
Dealing with scale is pivotal. It governs the extent to which we can
synthesize results across study areas, populations, and species. My lab
is working to develop techniques to understand and remove the effects of scale,
to allow us to make conclusions with greater generality.
I am dedicated to
communicating the science of ecology and conservation biology to
non-scientists. I am a Fellow with the Aldo Leopold Leadership Program
which advances environmental decision-making with a network of over
100 academic scientists.
Writing in
the popular press is one of my preferred avenues of public outreach.

Teaching and Postgraduate Training
At
Graduate
students in my lab are enroled in the interdisciplinary Environmental & Life Sciences Graduate
Program which offers instruction leading to either a M.Sc. or a Ph.D.
degree. Many of our projects are collaborative efforts with the Ontario Ministry of Natural Resources, Manitoba
Conservation, and the Newfoundland
& Labrador Department of Environment & Conservation.
Email me if you are a
prospective student looking for post-graduate opportunities.
