The 2021 APS Conferences for Undergraduate Women in Physics (CUWiP) are a set of regional conferences to be held January 15-17, 2021 at twelve different locations around the US with the aim of encouraging young women to continue in physics. Princeton University, in conjunction with the Princeton Plasma Physics Laboratory (PPPL), hosted the 2017 regional CUWiP covering Connecticut, Delaware, New Jersey, Pennsylvania, New York, Vermont and Puerto Rico. We're looking forward to hosting again in 2021! More info at cuwip.princeton.edu
