. At the school, he started the master's degree in computational science. In 2016, he became Director of the Institut Mathicse and was founding Director of the Institut de Mathématiques in 2017. Abdulle was impassioned with modeling and numerical simulations in biology, chemistry, geology, and medicine. He notably contributed to the development of heterogeneous multi-scale methods. He developed methods for solving multiscale and ergodic stochastic problems. He also invented the Orthogonal Runge-Kutta-Chebyshev, which was used to solve stiff differential equations which were then generalized to multiscale stochastic systems. In 2005, Abdulle won the New Talent Award at the International Conference on Scientific Computation and Differential Equations. He received an advanced research fellowship from the
