Présentation

I am currently working at the Mediterranean Institut of Oceanograpoghic as an senior engineer (IR CNRS) for high-pressure experimentation and instrumental development.My researches are focused on meso- and bathypelagic and microbial activities and specific diversity. I am interested about how microbes are involved in carbone cycle and which are main actors.

My main skills are

High pressure device development to collect sample or simulate deep sea conditions

Metabarcoding sequencing analysis and computeur sciences associated to analyse microbial diversity

Fluorescent in situ hybridisation and associated technics (CARD-FISH, MAR-FISH)

Statistics

Fields work

My research interest are :

Mircobial activities and diversity (free-living and attached to particles) in meso et and bathypelagic layer

Bioluminescent microbes associated to meso pelagic fishes
