Background and Research Interests

Wei Jia's main research interests are in nuclear astrophysics, particularly the nucleosynthesis of elements in the cosmos as well as nuclear reactions which take place atop or within accreting neutron star crusts. Her work at Lawrence Livermore National Laboratory combines low-energy nuclear physics experiments, performed at facilities such as the National Superconducting Cyclotron Laboratory (NSCL) and the ATLAS facility at Argonne National Laboratory, with microanalytic isotopic analyses of meteoric presolar grains performed in-house. Additionally, she utilizes nucleosynthesis network codes to investigate the impact of improved nuclear reaction rates on predicted elemental and isotopic abundances and to place constraints on astrophysical conditions in these environments.
