Formerly PhD student at University of Warwick...

PhD: Oct 2013-2017. Supervisor: Professor Richard Sharp.

Research interests:

Interactions between Dynamics and Ergodic Theory, Group Theory and Geometry. More specifically, the thermodynamic formalism for subshifts of finite type, with a view to the geometry of negatively curved manifolds. In my PhD I have studied the relationship between geometrical/dynamical data of regular covering manifolds, the spectrum of group extended transfer operators, and Kazhdan distances for representations.
