Timo Jolivet's research page


I am a postdoctoral researcher in the natural computing team (CANA) of the Laboratoire d’Informatique Fondamentale de Marseille (LIF), at Aix-Marseille Université. I am funded by the LabEx Archimède during 2016-2017.

During 2014-2015 and 2015-2016 I was a postdoctoral researcher at the Institut de Mathématiques de Toulouse at Université Paul Sabatier, funded by LabEx CIMI. During spring 2014, I was visiting Montanuniversität Leoben and TU Graz (Austria). I defended my PhD thesis in November 2013, under the co-supervision of Valérie Berthé (Université Paris Diderot, France) and Jarkko Kari (University of Turku, Finland).
