Program Officers List

These are the points of contact for research programs, typically current or former ROSES program elements. We deliberately maintain names of some old programs that are not solicited this year so that those who have continuing grants from those programs know whom they may contact for information or concurrence.

Scroll down the entire list below, starting with Astrophysics and moving through each Division, or jump to the Division of choice through the links at the top of the table. Can't find a person or a program on the list below? Please contact the R&A Lead of the relevant Division or contact the Science Mission Directorate R&A Lead Max Bernstein at max.bernstein.
