Magali Remaud-Siméon graduated from  the National Institute of Applied Science of Toulouse in 1985 and received  her PhD in 1988. Then she was as Post-Doctotal Fellow at the University of  Pensylvania where she worked with Prof D. Graves in the department of  Chemical and Biomolecular Engineering. From 1990 to 2000, she was an  associate professor at the Institute of Technology of the University of  Toulouse in the department of Applied Biology. Since 2001, she is a professor  at the National Institute of Applied Science of Toulouse. As the head of the Enzyme  Molecular Engineering and Catalysis group since 2001, she focuses her research activities on enzyme engineering for white biotechnology, green  chemistry, Food/Feed industries and synthetic biology. Her areas of interest  cover enzyme structure/activity relationship studies, kinetic resolution,  evolution combining both rational and combinatorial approaches, and  applications to the synthesis of  new  polysaccharides, oligosaccharides, glycoonjugates, esters and enantiopure  compounds.  She has been working on glucansucrases from GH family 70 and 13 since 1985. With her collaborators, she has  elucidated the mechanism of dextran, alternan and  amylose biosynthesis by dextransucrase, alternansucrase and amylosucrase,  respectively. Her work is currently focused on the search and generation of  enzymes displaying new specificities and improved properties towards  unnatural substrate.
