Papers are listed from newest to oldest. Authors are listed alphabetically by last name, except where indicated by an asterisk. Scientific journals are underlined.

Paper awards go by different names at different conferences (e.g., distinguished, outstanding, best …). I use “Best Paper” below to mean the highest award conferred at the conference.
