The Paris-Saclay MICROBES day, held on Wednesday March 27th 2019 at Gif-sur-Yvette, will showcase the diversity of Microbiology research performed at Paris-Saclay University. This event gathers a community of experts exploring the multiple facets of Microbiology (bacteria, archaea, microbial eukaryotes & viruses) across all scales: from molecules to genes, genomes, cells, populations, communities, and from basic sciences to applied innovations in microbial and molecular engineering and from environmental to human health.

This meeting is organized in 4 sessions of invited and selected oral presentations and a poster session (detailed program below).

Microbiologists from Paris-Saclay are invited to submit an abstract for an oral or poster presentation before Februray 20th (submission site closed).

FREE but mandatory registration (for trophic reasons... to prepare lunches, coffee breaks, etc)

Key words: microbiology – molecular and cellular biology – microbial ecology and evolution – biochemistry and structural biology - omics - applied and environmental microbiology – clinical microbiology – interdisciplinarity

Language: English

Place : I2BC auditorium, Bât. 21, CNRS Gif-sur-Yvette (see :
