Yann Chaubet
I am assistant professor (maître de conférences) at the
LMJL (Nantes Université).
Before that, I was Herchel Smith Research Fellow at the
DPMMS (Cambridge University).
My P.h.D
thesis was defended at the
LMO (Université Paris-Saclay) and was supervised by
Colin Guillarmou.
Here is my
CV.
Research interests
I study certain zeta functions associated to hyperbolic dynamical systems (geodesic flows in negative curvature, billiard flows) and their link with the underlying topology ; those functions are studied with the help of functionnal and microlocal analytic tools, through the prism of Pollicott-Ruelle resonances.
