Post-doctoral scientist position: “Entrapment of probiotics in polymeric gels”
• Half-time work at "PAPC laboratory, UMR PAM, Agrosup Dijon-University of Burgundy"
Development of self-gelled biopolymer gels (protein/polysaccharide) containing bacteria and impact of entrapment on the viability and persistence of probiotic bacteria along the gastro-intestinal tractus (in vitro).
• Half-time work at "Probihôte, Institut Micalis, INRA Jouy-en-Josas, France"
Impact of entrapment on the efficacy of probiotic bacteria screened by cells models and in vivo by murine models.

PhD thesis: “Entrapment of lactic acid bacteria (LAB) in polymeric matrices for a bioprotective application against Listeria spp.”
• Two years of work at BIODYMIA, Lyon1 University, Bourg-en-Bresse, France
Screening of bioprotective LAB against Listeria spp./purification and identification of antimicrobial active peptides/LAB cells entrapment in liquid or gelled bipolymeric matrices, viability and anti-Listeria activity during 12 days.
• One year of work at "PAPC laboratory, UMR PAM, Agrosup Dijon-University of Burgundy"
Study of microstructure and cells localisation of liquid and gelled matrices.

2010 Research Engineer, Ulice (Limagrain Céréales Ingrédients), Riom, France
• Six month-Industrial Placement in an industrial research centre to characterize and analyze functionalities of raw grain.
I made the scientific monitoring about the project “modification of grain substrates (starch) using enzymes”, developed the methods, made and planed the experimentations. I analysed and presented the results.

Research Assistant, Copenhagen University (LIFE), Food Science Department – Copenhagen, Denmark
• Three month-research placement in antioxidants.
I participated in the project “Screening of potential antioxidants for food systems”. I worked and wrote my report in English. I participated in the results analysis.
