Curriculum Vitae: Kiran Sridhara Kedlaya
All chronological lists sorted in reverse order; when an item corresponds to multiple dates, I sort using the most recent start date (and in case of a tie, the most recent end date, and in case of a further tie, alphabetically).
I also maintain a PDF version, but I don't promise to keep the two in sync. If you need a very current PDF version, please contact me directly.
