The Team

MIXOPEAT includes several European collaborators

Laboratoire Ecologie Fonctionnelle et Environnement (Toulouse)

Vincent Jassey (CNRS researcher, PI) 

Vincent is a microbial ecologist working on the diversity and function of microorganisms in food webs and ecosystem carbon and nutrient fluxes.


Régis Céréghino (Prof.)

Régis an ecologist interested in how natural environments and anthropogenic perturbations affect networks of biological interactions and influence community diversity


Joséphine Leflaive (Ass. Prof.)

Joséphine study of the factors structuring microbial communities and the response of the latter (diversity, richness, resistance, resilience, productivity, functioning) to biotic and/or abiotic disturbance


Gaël le Roux (CNRS researcher)

Gaël works on Isotope and Trace Element Biogeochemistry of the critical zone, especially in high altitude and high latitude areas


François de Vleeschouwer (CNRS researcher)

François aims at tracing environmental changes using elemental and isotopic geochemistry in continental archives (peat bogs, lake sediments). He also aims at reconstructing natural and anthropogenic dust fluxes and sources during the Holocene while assessing the impact of dust on climate and environment.


Maialen Barret (Ass. Prof.)

Maialen is interested on the diversity of methanotrophs in arctic, subarctic and subantarctic ecosystems, and in particulalry, how they respond to climate changes.



Samuel Hamard (PhD student)

Samuel will study the diversity, physiology and function of mixotrophic protists  living in Sphagnum mosses.  Especially, how the feeding balance of mixotrophs (photosynthesis vs. predation) influence the carbon fluxes of peatlands.

Anna Sytiuk (PhD student)

Anna will study the diversity, community and trait composition of the vegetation, especially Sphagnum mosses. 


Janna Barel (Postdoctoral Research associate)

The soil is full of life. Beneath our feet microscopic organisms perform all sorts of tasks. As a soil ecologist I am interested in understanding how soil communities function, how they respond to changes in their environment and how plants and soil organisms interact. As post-doc in the MixoPeat project I quantify the changes in structure and functioning of microbial food webs associated to Sphagnum (peat moss) in response to change in climatic conditions.

METIS (Paris)

Frédéric Delarue (CNRS researcher)

Frédéric is a geochimist working on the dynamic of labile and recalcitrant organic matter in ecosystems using chemical (Raman spectroscopy, 13C NMR, elemental analysis) and structural (HRTEM) techniques. He is also working on fossils using transmitted light microscopy, scanning electron microscopy, Raman microspectrometry, and nanoscale secondary ion mass spectrometry (NanoSIMS) ion microprobe analyses.

Consejo Superior de Investigaciones Cientificas ( Madrid)

Enrique Lara (Ass. Prof.)

Enrique studies the ecology, diversity, biogeography and evolution of microbial eukaryotes in general, using from classical culture/morphological approaches to molecular phylogenetics /-omics and environmental DNA surveys in terrestrial, freshwater and marine systems

Ecole Polytechnique Fédérale de Lausanne (EPFL)

Constant Signarbieux (Scientific collaborator)

Constant studies plant phenology and ecophysiology in grasslands, forest and peatlands. He is an expert of plant photosynthesis, including mosses.

University of Zurich

Owen Petchey (Prof.)

Owen research interests are predictive ecology, population, community, and ecosystem ecology; effects of environmental change; modelling biological systems; and statistical computing

Swiss Federal Research Institute WSL (Birmensdorf)

Konstantin Gavazov (Senior Post-doc)

Konstantin is interested in the impacts of climate change on cold-adapted ecosystems in relation to vegetation community dynamics and carbon cycling. He focuses on the interplay between carbon and nutrients in the circumpolar region where permafrost thaws and becomes rapidly colonised by higher plants, as well as in mountain areas where treelines expand and traditional land use changes

Radboud University

Bjorn Robroek (Lecturer)

Bjorn’s research focuses on the interactions between plant communities and belowground (microbial) communities, with a special interest in the effects of environmental change on plant-soil interactions.

Adam Mickiewicz University (Poznan)

Mariusz Lamentowicz (Prof.)

Mariusz’s interests are focused on ecology and long-term ecology of wetlands with a special focus on protists. I am applying the experimental and palaeoecological approaches to better understand the present and past global change and the carbon cycle. My current projects experimentally test the response of peatland ecosystems to drought and climate warming as well as synthesise historical geography aspects with palaeoecological perspectives.

University of Eastern Finland

Eeva-Stiina Tuittila (Prof.)

Eeva-Stiina focuses on the interactions between peatland plant communities and microbial communities under climate changes.

Swedish University of Agricultural Sciences (Umeå)

Paul Kardol (Ass. Prof.)

Paul investigates community dynamics, both under natural conditions (e.g. succession) and as affected by human impacts. Particularly, he focuses on the linkages between plant communities and soil communities and the consequences of plant-soil interactions for ecosystem functioning.

Climate Impact Research Centre (Abisko)

Ellen Dorrepaal (Ass. Prof.)

Ellen is a plant ecologist with a passion for the ecosystems of cold areas. She is fascinated by their characteristic plant communities and by the plants’ abilities to survive harsh conditions through manipulation of their neighbours and their micro-environment

Tallin University (Tallin)

Martin Küttim (Early-stage researcher)

Martin is a peatland ecologist working on the ecology of mosses, and especially how mosses cope with winter climate changes.  


Liisa Küttim (Early-stage researcher)

Liisa is a peatland ecologist, specialist of diatoms.
