I am interested in the Morse theory of the moduli space of riemannian metrics and its Gromov--Hausdorff closure (including connected-ness and disconnected-ness of sub-level sets of geometric functionals, such as the diameter or volume functionals) and the space of left-invariant metrics on Lie groups and homogenous metrics on riemannian manifolds and their variational calculus. In my thesis, I study the scaling-invariant thicknessnullof left-invariant metrics on Lie groups. Quite unexpectedly, the bi-invariant structures of many simple Lie groups are not local minima.
