I am an associate professor at Indiana University, Bloomington. I study low-dimensional topology, particularly finite-type invariants and geometric 3-manifold topology. I received my Ph.D. in 2000 from the University of California, Berkeley; my advisor was Vaughan Jones. Before Indiana, I was at Harvard and Barnard for some years, and Cornell, Tokyo Institute of Technology, and Berkeley for shorter terms.
I am an editor of the newly-formed journal Quantum Topology, published by the European Mathematical Society. We are currently looking for submissions for the first issue.
