Post-Doc Disentangling impacts of multiple stressors on biodiversity, ecosystem functioning and services in streams

Presentation

My research aims at understanding how global change can affect communities, ecosystem functioning and ecosystem service delivery in freshwater ecosystems. I am particularly interested in 1) identifying the environmental factors that are into play, 2) getting a mechanistical understanding of the factors regulating ecosystem functioning and 3) assessing the risks on the provision of ecosystem services. I work with field-based experiments as well as laboratory experiments. In my research, I apply and develop a species trait framework and, I bring in concepts from spatial ecology and resilience theory.

Teaching

TA for the Environmental Impact Assessment course at Uppsala University (part of the MSc in Sustainable Development)

Workshop organizer for PhD students: "Write your thesis summary"

Cooperation

I have on-going collaborations with:

- Pr Timo Muotka, Univeristy of Oulu

- Pr Helmut Hillebrand, University of Oldenburg

- Dr Romain Sarremejane, INRAE Lyon

- Dr Jussi Jyväsjärvi, University of Oulu

I am also an active member of the European COST Action SMIRES.

Background

I graduated from the Swedish University of Agricultural Sciences (Department of Aquatic Sciences and Assessment, Uppsala) in 2018. My PhD project was on Ecosystem functioning in Streams under Pressure. My main PhD advisor was Brendan McKie.

I got my Master degree in Ecology, Evolution, Biodiversity and Biometry from Lyon University (France) in 2011. I did my Master Thesis at Uppsala University working on phenotypic responses of Perch (Perca fluviatilis) to environmental changes and on predator-prey interactions in aquatic ecosystems.

I used to work as a lab and research assistant (SLU and Uppsala University) and as a study leader in a consulting and engineering office in France.
