Ann-Cecilie Larsen is a Professor in Nuclear and Energy Physics at the University of Oslo, leading research in nuclear physics and astrophysics. She works with the Oslo Cyclotron Laboratory (OCL) and collaborates with institutions like Université libre de Bruxelles, Lawrence Livermore National Laboratory, and CERN's ISOLDE facility. Master of Science in Physics, University of Oslo (2002) Cand.scient. in Nuclear Physics, University of Oslo (2004) Ph.D. in Nuclear Physics, University of Oslo (2008) Her research focuses on nuclear properties at extreme temperatures, particularly level density and gamma decay functions. These studies inform astrophysical reaction rates for understanding cosmic element formation. She teaches FYS-MEK1110 - Mechanics and KJM-FYS5920 - Nuclear Measurement Methods . Recent publications analyze nuclear decay patterns in Sn isotopes, neutron interactions on 89Y, and shape coexistence in rare isotopes. Her work connects nuclear structure studies with stellar nucleosynthesis. Prize for Young Outstanding Researchers, Norwegian Research Council (2016) Fulbright Scholarship (2015) ERC Starting Grant (2015-2020) Best Poster, Zakopane Conference (2006) She holds a Research Council of Norway project (2021-2026) and has previously received personal postdoctoral funding (2011-2014). Collaborations include Facility for Rare Isotope Beams, ISOLDE@CERN, IReNA, and ChETEC-INFRA networks.
