Post Doc

I’m in post-doc with Fabrice NOT, evaluating impacts of environmental change on planktonic photosymbioses.

RESEARCH TOPICS

I’m interested in plankton-environment interactions, using system biology to decipher response to environmental changes at different scales: from genes to communities. Believing that genetic is a powerful tool to study such responses, I developped bioinformatic skills and use particularly RNA-Seq, barcoding, metagenome and metatranscriptome analysis.

PROJECT OUTLINES

My post-doc project is funded by the ANR IMPEKAB which aims at i- evaluate the sensibility of planktonic photosymbiosis to environmental changes, ii- unveil fundamental biological processes involved in the response of photosymbiosis to thermal stress across eukaryotic lineages, and iii- apply an original eco-systems biology approach to evaluate the thermal stress response of planktonic photosymbiosis in the environment.
During my post-doc I’ll focus on response of Collodarians to thermal stress. I’ll perform a stress experiment at lab and measure/analyse as well physiological (photosynthesis and respiration) as molecular response (metabolome and transcriptome). Using such a comprehensive approach, I’ll try to highlight potential candidate genes reflecting response to thermal stress so as to extend our analysis to natural ecosystems.
