Blandine Galiay's webpage
Welcome on my webpage!
I am a CNRS Researcher at the IECL (Nancy).
I completed my PhD at IHES with Fanny Kassel. My PhD project was Geometry of proper domains in flag manifolds. You can find my CV here.
My research interests include discrete subgroups of Lie groups and their links with geometric structures, convex projective geometry, (higher) Teichmüller theory, Anosov representations...
