Biographie
Assyr Abdulle est professeur ordinaire de mathématiques a l'EPFL et titulaire de la chaire d'analyse numérique et de mathématiques computationnelles.
Originaire de Laconnex (Genève), Assyr Abdulle est né en 1971. Il a obtenu un diplôme professionnel de violon au Conservatoire de Musique de Genève en 1993 et un Doctorat en Mathématiques à l'Université de Genève en 2001.
Il effectue sa première année post-doctorale à l'Université de Princeton (Etats-Unis) et a occupé successivement des postes de chercheur associé, professeur assistant et professeur associé à l'ETH de Zurich, l'Université de Bâle ainsi qu'a l'Université d'Edimbourg.
Il a reçu le prix "SciCADE new talent" en 2005, un "Advanced Research Fellowship" (ARF) du conseil de recherche "Engineering and Physical Sciences Research Council" (EPSRC, Royaume-Uni) en 2007 ainsi que le prix Wilkinson (SIAM) en analyse numérique et calcul scientifique en 2009.
Ses recherches portent sur le développement, l'analyse et la mise en uvre de méthodes numériques pour les équations différentielles multi-échelles ordinaires, aux dérivées partielles ou stochastiques. Assyr Abdulle élabore des méthodes computationnelles applicables à la simulation de nombreux problèmes dans les domaines des sciences naturelles et de l'ingénieur.
