    Graduate Student Combinatorics Conference 2007
     
    I helped (with Brant Jones, Matt Kahle, and Beth Kelly) to organize this past year's GSCC, held at the U of Washington in Seattle on April 21-22, 2007.
    Check out the attractive conference poster here (warning: big file).
     
    other writings/songs
     
  • Metaphors of the contemporary city
  • A cognitive approach to the equivalence relation (under construction)
  • My personal network is a wedge of circles (up to homotopy type)
  • Here is something I wrote for the Demonstrations project organized by artist Lun-Yi Tsai in Seattle in 2007.
