Om

I am a terrestrial ecosystem ecologist and land surface modeler interested in the feedback cycles of global climate change and ecosystem carbon cycles. My work focuses on understanding how climate and environmental changes affect ecosystem structure and function, particularly ecosystem C cycling. My recent research interests involve climate change impacts on nature and society. I am particularly interested in how climate change affects people’s lives in high latitude ecosystems and how our efforts to mitigate affect future climate and ecosystems.
