Initially hired in 2009 to identify stream invertebrates, I quickly grew to love freshwater ecology. While working for Dr. Palen, I was given the opportunity to work on many collaborative projects ranging from population estimates of amphibians to predator removal experiments. Through these projects, I developed an interest in the conservation of the beautiful landscapes where I often found myself.
My graduate studies were through UBC with Dr. Palen on my committee. During that time I was interested in the ecological impacts of run-of-river hydropower. While run-of-river hydropower is arguably less impactful on the environment than coal or oil-based electricity production, the long-term impacts on ecosystems are not well studied. As Coastal Tailed frog tadpoles can live up to 4 years in streams, I investigated if run-or-river operations could have population level impacts. In turn, this research will help inform mitigation and adaptive management of the run-of-river industry.
