Loïs Maignien - Associate Professor
Microbial ecologist seeking to understand how microbes change their environment... or maybe the other way around.

They do the job:

Feriel Bouderka - MSc. student

Advised by Blandine, Feriel is looking at Arachaea diversity and distribution in the Abyssal and Hadal environment, as part of IFREMER's "ABYSS" project

Blandine Trouche - PhD student
Blandine is working on abyssal sediments microbial ecology and biogeography with amplicon and metagenomics approaches. She will use samples collected as part of IFREMER's "ABYSS" project, sequenced at the Genoscope through a France Genomique "eDNAbyss" grant.
Read her MSc. thesis repport on metagenomics binning  here

Clarisse Lemonnier - Postdoc
Clarisse is looking at community assembly on plastic particles in the Bay of Brest. She will use her great knowledge from the Brest Bay microbial observatory she has devlopped during her PhD.

Ashley Grosche - Postdoc

After completing her PhD work at Rutgers on deep-sea hydrothermal vents microbiology, Ashley has joined our group to elucidate deep subsurface microbial processes in CO2 injection well, as part of the european project " Science for Clean Energy"


They did a great job

Florian trigodet
Florian Trigodet- PhD student 2016-2019
Florian has been investigating the electroactive behavior and community assembly of marine biofilms that form on conductive surfaces. Florian is now postdoc in Meren Lab at U. Chicago.

Damien Courtine - PhD Student 2014-2017
Damien graduated in 2017 with his PhD defense on the diversity, ecology and evolution of extremophiles through the lens of  genome sequencing and comparison. Damien is now postdoc at the turing center for living systems in Marseilles

Sabrina Berlendis - Postdoc
Sabrina has been carrying research on the Bacterial and Archaeal commmunity structure along steep salinity gradients of Mediteranean sea deep hypersaline lakes.

Arnaud Fichant - IUT internship
April 2017, 2.5 month

In an internship for the University Institute of Technology, and under the lab supervision of Nadege Quintin, Arnaud cultivated several Thermococales and Thermus isolates and sequenced their 16S rDNA genes. These strains will now be able to join our public marine collection. Read his report here (french)

Julien Barillere - IUT internship
April 16 2015, 2.5 month

In an internship for the University Institute of Technology, Julien participated to our long term coastal microbial observatory, from sea water sampling to 16S Illumina library preparation. He planned and supervized our "tidal" experiment, in which microbial communities variations were evaluated over a full tidal cycle

M. Galant - IUT internship
April 16 2015, 2.5 month
In an internship for the University Institute of Technology, M. Galant   cultivated and sequenced 16S rDNA genes  in order to examine phylogenetic reationships among our rich Thermococales isolates collection. Read  her report here

Nolwen Leost - IUT internship
April 1 2014, 2.5 month
In an internship for the University Institute of Technology, Nolwen started tens (soon hundreds!) of cultures from our hyper thermophile strain collection, with the aim of sequencing their 16S rDNA gene. All these bugs that spent years in the limbos of the -80° freezers will soon receive a name. Thanks Nolwen!
