Timo Jolivet


I am a postdoctoral researcher at the Institut de Mathématiques de Toulouse at Université Paul Sabatier, funded by LabEx CIMI during 2014-2015 and again during 2015-2016. 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). During spring 2014, I was visiting Montanuniversität Leoben and TU Graz (Austria).
