Biography

Rahul Jain’s research interests are in the field of nuclear astrophysics including nuclear experiments and statistical analysis of nuclear data. His PhD thesis work at Michigan State University (MSU) was based on the experimental b-decay of 33Mg including b-delayed g and neutron emission using Total Absorption Spectroscopy (TAS) to constrain the rate of Urca cooling in accreting neutron star crusts. His thesis also included constructing a data-driven nuclear mass model using Bayesian Machine Learning techniques for accurate modeling of neutron star crusts. As a graduate student at the Facility for Rare Isotope Beams (FRIB) at MSU, he participated and contributed to multiple nuclear physics experiments using a variety of experimental set-ups including the SECAR Recoil Separator, FRIB Decay Station initiator (FDSi), AT-TPC Time Projection Chamber, GADGET-II, etc.

As a postdoc at Lawrence Livermore National Laboratory (LLNL), he is developing a new indirect measurement technique using the upcoming tritium beam facility at Florida State University (FSU) to experimentally constrain the neutron-capture cross sections on unstable nuclei for heavy element nucleosynthesis in the slow neutron-capture process (s-process). He is using the Super Enge Split Pole Spectrograph (SE-SPS) and the CeBrA g-ray detector array at FSU for these measurements. Additionally, he is also building ‘ReacTool’ to simulate spectra from nuclear reactions that can aid in experimental design and planning.
