Laurent Fontaine

Background

I have joined the section for Aquatic Biology and Toxicology as a PhD student under the supervision of Alexander Eiler. I have a background in biology from Université Laval (Canada) and as an exchange student at UiO. I have been focused on microbial ecology and biogeochemistry during my master studies where I studied bacteria and ectomycorrhizal fungi involved in mineral weathering and their role in plant nutrition in boreal forests. These microorganisms form a tripartite association with trees where the plant host provides sugars to the fungal partner acting as a nutrient transporter between the tree and mycelium-associated mineral-weathering bacteria.

I will be working on environmental genomics of northern lakes in the context of climate change, with particular attention on increased input of terrestrial dissolved organic matter. The structure and functions of freshwater bacterial communities will be coupled to water quality properties and gas fluxes in a model meant to predict ecosystem processes such as greenhouse gas emissions.
