Biography / Academic Interests
Joseph Maher is interested in geometric topology, particularly in the study of surfaces and three-dimensional spaces, and random walks on groups. Other topics of interest include knots, hyperbolic geometry, and the collection of all maps from a surface to itself, which is known as the mapping class group of the surface. This group has interesting large scale geometry, and is closely related to the space of all hyperbolic metrics on a surface, known as Teichmüller space.
