Professional History

My main areas of research are Hyperbolic geometry, Kleinian groups and Teichm├╝ller theory. One interest is the relation between the convex hull of a Kleinian group and its conformal structure at infinity. Another is the interplay between the conformal dynamics and Kleinian groups via Patteron-Sullivan theory and geodesic currents, in order to develop structures and invariants for hyperbolic spaces and their moduli spaces. One such structure of interest is to extend the classical Weil-Petersson metric on Teichm├╝ller space to other moduli spaces such as Quasifuchsian space and Schottky space.
