I am broadly interested in how freshwater microbial communities are influenced by their biotic and abiotic environment, and using this information to make informed predictions about past, present, and future ecosystem structure and function. I am particularly interested in links between microbial composition and biogeochemical cycles, and how these relationships will evolve given global climate destabilization, land-use change, and ever-increasing socio-economic disparities.
Polar regions in particular are ideal places to disentangle these relationships, given their relatively pristine nature and trophic simplicity. Furthermore, rapidly accelerating environmental change and an increasing human presence makes research in these areas especially timely.
