My research subjects focus on the ecology of shallow lakes and wetlands and the role of abiotic conditions on their functioning. In particular, I study the effects of water column mixing, inputs of allochtonous organic matter and temperature changes on shallow lake and wetland dynamics.

Water column mixing depends on the wind regime through wave formation and, according to its intensity, it may suspend organic matter and nutriment that have settled in the benthic zone in shallow lakes. Freshwater organisms and their interactions may be affected by an increase of turbidity affecting photosynthesis for instance and resource inputs (nutrients, organic matter) in the pelagic zone. Inputs of allochtonous organic matter may also affect the dynamics of aquatic organism dynamics and food webs. Global changes may affect these abiotic conditions. Climate change can modify water column mixing through wind regime alteration. In addition, increased temperature stimulates water evaporation that changes water level and amplifies the effects of waves on resuspension. Changes in land use and rainfall patterns (intensity, frequency) also affect runoff and inputs of terrestrial organic matter in aquatic ecosystems. Understanding the effects of climate change changes on water column mixing and inputs of terrestrial organic matter in freshwater ecosystems in interaction with land use change are current challenges.

I use two complementary approaches: experiments in controlled systems and field studies. In my last projets, mesocosm experiments were realised in collaboration with the Planaqua platform in Cereep Ecotron – IledeFrance (https://www.cereep.bio.ens.psl.eu/). Field studies were conducted in Hwange National Park, Zimbabwe, in collaboration with the Hwange LTSER (Long-Term Socio-Ecological Research site) (https://www.za-hwange.cnrs.fr/?page_id=130&lang=fr).

I teach for 3rd year student and graduate students in the master program Biodiversity Ecology and Evolution. I teach community ecology, functional ecology, aquatic ecology and ecotoxicology.

Pedagogy training

I also organize, in collaboration with colleagues from different department of the university, formation to pedagogy for doctoral students and newly recruited lecturers.

Responsabilities in teaching

I am co-responsible of the 3rd year program Organism Biology and Ecology (around 150 students), responsible of the teaching unit “Community and ecosystem ecology” and co-responsible of the teaching unit “Chemical risks and ecotoxicology”. In the master degree, I’m responsible of the 1st year internship and co-responsible of the teaching units “Professional integration” and “Ecological engineering”.

In the Biology Department, I’m correspondent for Ecology|Botany.
