I am an instructor in Geography at UBC. My teaching specialty is in Physical Geography, including biogeography, soils, weather and climate. My research explores vegetation dynamics and how these are affected by human activities, particularly in relation to ecosystem fragmentation, altered disturbance regimes and invasion, and interactions with climate change. I study population dynamics in forests and savanna of eastern North America and the Karakoram-Himalaya. Currently I am examining potential range shifts among high alpine plant populations of the Central Karakoram.
