I am a biogeographer with research specializing in seed dispersal and colonization, ecosystem fragmentation, and species migration in human dominated landscapes under changing climate. I have enjoyed learning about ecosystems through field research, beginning with my undergraduate thesis work in the Truelove Lowland, Devon Island, where I studied arctic plant populations in meadows and raised beach ridges of the lowland. I went on to work in temperate forest and savanna ecosystems in North America, in subalpine forests and alpine meadows of the Western and Central Karakoram-Himalaya, and most recently, southern BC. I aim to apply this research experience to assist with policy, management and to educate about these systems.
