Research Interests

My initial interest in research began with a fascination of the study of insects in the field. It wasn't until I spent three months backpacking and collecting bees in the southwestern desert of Utah, that I found myself interested in bee research. Today, my interests have shifted more specifically towards bee biodiversity, taxonomy and conservation biology. For my Master's I will be determining how bee biodiversity and community composition has changed over a 33-year period, as a result of global warming, succession, and other anthropogenic influences. I will be repeating the only historical study done on Canadian bee biodiversity in 1968/1969, in an old field habitat at the Forks of the Credit River. Bees collected in this study will be entered into a "Bees of Canada" database, that I will be constructing, aimed at documenting the poorly known bee fauna of Canada. This will be the first database available for future reference for bee biologists, ecologists, botanists, taxonomists, and conservationists.
