Past Chairs

The U.S. National Committee (USNC) for the International Union of Radio Scientists (URSI) is appointed by the National Academies of Science, Engineering, and Medicine (NASEM). USNC-URSI is led by an Executive Committee consisting of the Chair, Immediate Past Chair, Secretary/Chair-Elect, and Accounts Manager. Prior to 1999, the roles of Chair-Elect and Secretary were separated.

The full USNC-URSI Committee is comprised of the Executive Committee, each of the ten USNC-URSI Commission Chairs, representatives to various professional societies and government agencies with interests in Radio Science, and six Members-at-Large.

This page lists those USNC-URSI members who have had the honor to be elected by their peers to serve as Chair of USNC-URSI.
