Françoise Debart obtained her Ph.D in Chemistry from University of Montpellier in 1989 in the laboratory of Prof. J.-L. Imbach, expert in the field of the chemistry of Nucleic acids and its components. In the same year, she joined the French National Center of Scientific Research (C.N.R.S) as an Associate Researcher. From 1990 to 1992, she was a post-doctoral fellow at Isis Pharmaceuticals (California, USA) in the field of antisense oligonucleotides. She then returned to Montpellier in Imbach’s group and she worked on backbone-modified DNA oligonucleotides. In 2003, she moved from DNA chemistry to RNA chemistry and she focused her research on new methodologies for synthesis of modified RNAs. Since 2011, she has been a Director of Research at CNRS working at the Institute of Biomolecules Max Mousseron (IBMM). Her research interests focus on the synthesis of modified RNA oligonucleotides as valuable tools for therapeutic applications and for understanding the RNA machinery. She is recognized as an expert in the synthesis of 5'-capped RNAs bearing modifications.
