Title:     Precision Frontiers of Big Bang Nucleosynthesis

Abstract: Big Bang nucleosynthesis (BBN) describes the cosmic production of the lightest nuclides, such as D, He4, and Li7, in the first minutes of cosmic time. Based on the comparison of light element abundance predictions and observations, BBN probes the physics of the early universe and provides constraints on important cosmological parameters, in particular, the baryon density and the effective neutrino species. In this talk, I will present my past PhD work on the precision frontiers of BBN in response to the latest developments in key nuclear reaction experiments, astronomical observations for primordial abundances and the cosmic microwave background measurements. I will also give a brief discussion of future BBN projects that I expect to do here at TRIUMF.
