Matthieu joined the TSF team (Dependable computing and fault tolerance) at LAAS-CNRS in 2004, after obtaining a PhD from the University of Rennes I on distributed algorithms. He received the Habilitation à Diriger les Recherches in 2018.

He leaves his colleagues with the memory of a brilliant mind, curious about everything and extremely open in his choice of research topics. He was capable of embracing both highly theoretical subjects, such as the links between algebraic topology and distributed systems theory, as well as highly experimental ones, such as the capture and analysis of human mobility data. His contributions have been rich, notably in distributed algorithms, adaptive fault tolerance, real-time computing on multicore architectures, and dynamic graphs. He liked working on topics at the intersection of different subfields of computer science and/or on multidisciplinary topics. His collaborations included projects with researchers in ethology, theoretical physics, economics and aerology.

Matthieu's human relations were as open as his research approach. He was able to mix with people from all backgrounds, and was unanimously recognized as an engaging personality.

Matthieu was passionate about teaching, and lectured at the highest level in many French universities and Grandes Ecoles. He attracted excellent PhD students whom he co-supervised and who benefited from the relevance of his ideas.

The TSF team loses a colleague and a friend. We offer our sincere condolences to his four children, his parents and all his close relatives.

Leave a gesture of sympathy.
