Overview of Current Research
Paper birch (Betula papyrifera) has become recognized for its high quality fiber and economic value. However, the species remains grossly understudied in Canada. Due to the wide distribution of paper birch across North America, it exhibits an enormous degree of phenotypic plasticity. Thus, there is a large degree of physiological and morphological variance between populations and individuals. However, due to a lack of scientific studies it is currently unknown to what extent ecophysiological differences have on the productivity of paper birch in intensively managed plantation systems. Such knowledge can provide valuable insight for future selection/genetic improvement programs.
The goal of this study is to asses and compare the growth and physiological function of paper birch provenances at multiple sites in a common garden experiment across the region of Abitibi-Témiscamingue. The objectives of the study are to 1) identify the natural variability of phenotypic and physiological characteristics and 2) characterize the eco-physiological and environmental factors influencing rapid establishment, growth and morphology of paper birch provenances in plantations under intensive management.

I obtained an honours bachelor degree from Wilfrid Laurier in biology with a minor in geography. At this time I studied as an undergraduate thesis student with Dr. Jennifer Baltzer . My research investigated the symbiotic relationship between the nitrogen fixing bacteria, Frankia, and green alder (Alnus viridis). The aim of the project was to better understand whether nutrient dynamics strongly influence the proliferation of green alder across the Arctic tundra.
In 2016, I worked as a field assistant in Dr. Jennifer Baltzer’s Forest Ecology lab and collected data to better understand the underlying mechanisms that influence shrub expansion on the low Arctic tundra in the Northwest Territories.
In 2017, I worked as a research assistant in Dr. Jennifer Baltzer’s Forest Ecology lab. I spent three months in the taiga plains of southwestern Northwestern Territories, conducting research on the changes in plant community composition and structure in response to permafrost thaw in the boreal forest. In addition, I spent four months in the lab at the Cold Regions Research Centre processing and analyzing field samples.
