David Gabai is an American mathematician and the Hughes-Rogers Professor of Mathematics at Princeton University. Focused on

low-dimensional topology In mathematics, low-dimensional topology is the branch of topology that studies manifolds, or more generally topological spaces, of four or fewer dimensions. Representative topics are the structure theory of 3-manifolds and 4-manifolds, knot theor ...

and hyperbolic geometry, he is a leading researcher in those subjects.
