Patricia Cahn

I am a Hans Rademacher Instructor of Mathematics at the University of Pennsylvania, working in low-dimensional and geometric topology.  I received my PhD from Dartmouth College in 2012, where my advisor was Vladimir Chernov.  I received my BA in Mathematics, and a minor in music, from Smith College in 2006. 

Next fall I will be teaching Math 500 (Topology) and Math 104 (Calculus).

I will be at the Max Planck Institute for Mathematics in Bonn, Germany from January 1 until August 15, 2014.


I am interested in geometric and low-dimensional topology.
