Here you will find the rosters to study sections run by CSR. The rosters show who served on the panel in the past and can help clarify the expertise represented. Rosters of both special emphasis panels (to a greater degree) and of standing panels (to a lesser degree) change from meeting to meeting based on the expertise needed to review the group of applications referred to the panel.
This link will allow you locate scheduled CSR study section meetings by date, by Review Branches (RB), or by study section for the current review round. (This is primarily of value to NIH staff.)
