Welcome! Thanks a lot for agreeing to provide a reference for me.
How to use: Each entry below corresponds to an individual application for which separate action needs to be taken by the referee. Generic letters for platforms such as Academic Jobs Online or Interfolio, are not included here and will be negotiated separately by an email exchange. The applications are sorted in reverse chronological order, with the most recent ones first. You may wish to scroll the page to check whether you’ve missed anything, especially since notification for the earlier letters was handled by piecemeal emails.
Policy on tuning: Due to the number of applications, feel no pressure to tune each letter beyond the addressee, etc. That said, the applications are ranked/colored by importance. For more important applications, if you have time and energy in your busy schedule, I would be grateful for more tailored letters. If something special is called for, it is detailed in the notes and will be accompanied by additional email instructions.
If you miss a deadline: No worries! If you are able to let me know via email, however, that would be greatly appreciated.
