About

I have been working to understand the consequences of environmental change, driven by the changing climate, on Arctic tundra ecosystems through long-term observations and field experiments. Studies of plant growth, phenology and reproduction, biodiversity responses, biotic interactions, evolutionary and migration potential of plant species, carbon and nutrient fluxes, and effects of permafrost disturbance form the basis of investigations by my group. We also work in Arctic communities to help northern students understand and interpret observations of environmental change by elders through shared field and class experiences and participation in science-based projects on berry producing shrub species.

I have been working to understand the consequences of environmental change, driven by the changing climate, on Arctic tundra ecosystems through long-term observations and field experiments. Studies of plant growth, phenology and reproduction, biodiversity responses, biotic interactions, evolutionary and migration potential of plant species, carbon and nutrient fluxes, and effects of permafrost disturbance form the basis of investigations by my group. We also work in Arctic communities to help northern students understand and interpret observations of environmental change by elders through shared field and class experiences and participation in science-based projects on berry producing shrub species.
