I am an ecosystem ecologist.
My goal is to understand and predict how ecosystems are shaped by climate change. My work takes me from upland forests to soggy peatlands to thawing arctic tundra, chasing a better understanding of the secret lives of roots hidden beneath the soil surface.

All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.
