Mixed Hodge Numbers and Factorial Ratios
These are the slides of my talk at Bill Duke’s birthday conference held at ETH in Zurich. I later wrote an extended abstract of this talk. It includes a proof of the calculation of the mixed Hodge numbers of a hypergeometric motive. The original conjecture on Hodge numbers of is a paper of Corti and Golyshev. A proof was given by Fedorov.

Character Varieties II
These are the slides of my talk at the first Abel conference in honor of John Tate at the University of Minessota in 2011. It is a summary of my work with T. Hausel and E. Letellier.

Character Varieties I
These are slides of a talk of the late 2000’s (don’t remember where) on my early work with T. Hausel on character varieties. It has some details on the combinatorics involved in computing the key quantity $C_\tau$.

Explicit Elliptic Units
These are the slides of a talk I gave some time in 1997 on my joint work with Farshid Hajir on defining explicit elliptic units; basically trying, and to some degree succeeding, to tame the 24-th roots of unity that arise from the transformation formula of Dedekind’s eta function.
