Interests
I apply cutting-edge tracer techniques and molecular approaches to unravel the biogeochemistry and underpinning microbial ecology of a diverse array of aquatic ecosystems. From headwater streams in the Arctic, to the open-ocean Pacific and carefully controlled experimental systems to link cause to effect through climate warming. I also purse the unorthodox to reveal both new and unexpected biogeochemical cycling occurrences, where previously they would have been dismissed – i.e., anaerobic ammonia and methane oxidation in riverbed sediments would have seemed fanciful only 10-years ago and we now know that some ecosystems use the greenhouse gas nitrous oxide as a nitrogen source, changing our perception of ecosystem functioning.Publications
