Présentation
I am associate professor at the University of Reims Champagne Ardenne since 2006. I am conducting my research within FARE lab (Fractionnement des Agroressources et Environnement). This lab is a joint research unit between URCA and INRAE (the french National Research Institute for Agriculture, Food and Environment). Within FARE I belong to the AFERE (Agroressources, Fermentation et Enzymes) chair structure since its creation in 2016.
I am a microbiologist but I am interested in many scientific fields and have skills in biochemistry, molecular biology and enzymology. I am very interested in the field of biotechnology, either to find solutions for societal problems (concrete applications) or to gain knowledge and advance research.
The main topic of my research concerns plant biorefinery including the valorisation of biomass by biotechnological processes (enzymatic or microbial). To this end, I study the mechanisms used by microorganisms to efficiently fractionate lignocellulosic biomass and apply them in controlled bioprocesses. Thus, my work focuses on the characterisation of hemicellulolytic enzymes (pure or in mixed forms) and their applications on xylan to obtain sugars (C6 and C5 and xylooligosides) and ferulic acid,...For some years, I have been interested in the use of oxidoreductases for lignin transformation.
The other part of my activity is teaching; I teach in biotechnology and microbiology from bachelor to master degrees levels.
I am also involved in the supervision of numerous students (end-of-study internship to thesis supervision) and non-permanent staff (technicians, post-docs, engineers, etc.)
My interests are very diverse and range from the smallest microorganisms to the behaviour of animals in nature. I like reading (especially crime novels and fantasy fictions or anticipation), walking and running ( moderately), cooking and trying many recipes that I don't always succeed very well
