2025 Congressional Fellows reflect on their terms
Each year, the American Nuclear Society awards the Glenn T. Seaborg Congressional Science and Engineering Fellowship to two members. Those recipients then spend a year in Washington, D.C., contributing to the federal policymaking process by working in either a U.S. senator’s or representative’s personal office or with a congressional committee.
It has been nearly six months since the 2025 Congressional Fellows provided their midterm updates on their time on the Hill. Now, as their fellowships draw to their close, Jacob Christensen and Mike Woosley are looking back on what they accomplished, what they learned, and much more.

The motion of charged particles in slowly varying electromagnetic fields is analyzed. The strength of the magnetic field is such that the gyro-period and the gyro-radius of the particle motion around field lines are the shortest time and length scales of the system. The particle motion is described as the sum of a fast gyro-motion and a slow drift velocity.
