Biying Liu successfully defended her Ph.D. thesis on March 26, 2025, for her work towards high-precision mass measurements at the N = 126 Factory, advised by Prof. Maxime Brodeur. The N = 126 Factory is a new radioactive ion beam (RIB) facility that will enable high-precision mass measurements of exotic nuclei of relevance for the astrophysical rapid neutron capture process for the first time.
Biying performed final testing of the Notre Dame Multi Reflection Time of Flight (MR-TOF) mass spectrometer before commissioning it with stable and radioactive beams at Argonne, participated in multiple mass measurement campaigns with the Canadian Penning Trap at Argonne, and analyzed the most precise data set on the 28Al half-life at Notre Dame. Biying is co-author in 16 refereed publications including two where she is first author.
