Béatrice Clouet-d'Orval, is a Research Director at the Centre de Biologie Intégrative, Toulouse (CBI/CNRS/Université de Toulouse). She received her degree in Genetics and Biochemistry from the Université Pierre et Marie Curie, Paris, and subsequently obtained an EMBO fellowship for postdoctoral research at the University of Colorado, Boulder.

Béatrice Clouet-d'Orval believes that the emergence of model organisms permitting genome-wide approaches that allow for the study of RNA biology in Archaea represents a unique opportunity to obtain major insights into evolutionary conserved RNA processing pathways in the three domains of life. Her research interests include in vitro reconstitution of archaeal ribonucleoprotein complexes involved in tRNA modification, and identification and characterization of archaeal enzymes involved in RNA processing and degradation. In addition, she is also active in promoting networking between scientists working on RNA and Archaea.
