About

 

My research explores vegetation dynamics with a focus on the impacts of human activities, particularly ecosystem fragmentation, altered disturbance regimes, biological invasions and climate change. I am interested in finding solutions to manage these impacts. I study plant populations in ecosystems of eastern North America and the Karakoram Himalaya. My current and recent projects include examining potential range shifts among high alpine herb populations of the Central Karakoram; developing a mathematical model to predict tree species’ colonization potentials in fragmented eastern forests; assessing the policy of assisted migration to address the biodiversity threats of shifting bioclimatic limits; investigating invasive species’ responses to climate change; and studying fire history in eastern Black oak savanna to inform current fire management strategies.
