    Here are some expository papers/transparencies from talks that do a good job of what I've been up to in the past few years:

  • 1999: The symplectic and algebraic geometry of Horn's problem
  • 2003: Positivity, Effectivity, and Degeneration; my 2003 Keeler Lectures at University of Michigan
  • 2003: Four positive formulae for quiver polynomials my portion of a 3-person series of talks, based on this paper
  • 2004: Geometric vertex decompositions (pdf version) my FPSAC '04 talk, based on this paper
  • 2005: Torified simplicial posets from Samuel-Rees degenerations (pdf version) MIT algebraic geometry seminar, Feb 2005
  • 2005: Combinatorics of the Brauer loop scheme notes by my coauthor Paul Zinn-Justin from a talk Feb 2005, and
    Geometry of Weyl group representations and statistical mechanics, Caltech colloquium May 2005, each based on this joint paper
  • 2006: Limits of subvarieties: subschemes vs. branchvarieties (pdf version) MIT and Columbia algebraic geometry seminars, Feb 2006, based on this paper
  • 2007: Schubert calculus, matroids, and shifting Toronto colloquium, Sep 2007
  • 2008: The mathematics of juggling Secondo Festival della Matematica, Rome
  • I used to have my papers on this front page, but now I'm only showing off my coauthors. Most of them have the decency to come after me in the alphabet.
