Research areas

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. I am also really into citizen science and networking.

On-going Projects:

– DRYvER: ​Securing biodiversity, functional integrity and ecosystem services in DRYing riVER networks

– Microplastics in freshwater foodwebs: Evaluating properties, fates and individual-ecosystem level impacts​

– CROSSLINK: Understanding cross-habitat linkages between blue and green infrastructure to optimize management of biodiversity, ecosystem services and multiple human uses

– DISTRESS: DisEntangling the impacts of multiple Stressors on stream ecosystems.

– WATERS: studying the impacts of agriculture, forest management and hydropower dams on stream communities and ecosystem functioning.

– SMIRES: Science and Management of Intermittent Rivers and Ephemeral Streams

Supervision

On-going PhD-Students:

– Ze Hui Kong  (assistant supervisor): Microplastics in freshwater foodwebs

Past Master students:

– Anna Taskinen: The effects of drought and connectivity to freshwater benthic fauna (2015).

– Maisam Ali: Assessment of changes in algal biomass accrual and leaf decomposition along a gradient of increasing agricultural disturbance (2013-14)

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.

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.
