Welcome to Thomas Gobet's webpage !    


Position: I am an ARC supported postdoc in the Algebra research group of the University of Sydney, working under the supervision of Prof. Anthony Henderson. Here is my University of Sydney research profile page.

Before this I was an ANR supported postdoc in the Geometry team of the Institut Elie Cartan de Lorraine in Nancy, working with Pierre-Emmanuel Chaput. Before this I was a scientific collaborator in the Representation theory team of Gunter Malle at the University of Kaiserslautern. Before this I was a PhD student of François Digne in the Group theory team of the University of Amiens.
