Note: (1) You should name at least two program directors, whose title on the staff directory pages will generally be "Program Director", and who will be listed as "Contacts" on program pages. You should not name senior managers with the titles Director, Deputy Director, Office Head, Office Director, Assistant Director, Deputy Assistant Director, Division Director, Deputy Division Director, Section Head.
(2) The first listed program director will be initially responsible for coordinating NSF's reply to your inquiry. If you can determine one program that is the most impacted by your proposed research, it will usually be best to list one of the Contacts for that program as the first program director. The second program director should represent a different program.
