I am a graduate student studying theoretical particle physics.

My research is currently focused on precision theoretical calculations within the Standard Model, aimed at reducing theoretical uncertainties to match the increasing precision of modern particle and nuclear physics experiments. My current work investigates QED radiative corrections in neutron and nuclear beta decay. These high-precision theoretical calculations are crucial for the extraction of the CKM matrix element $V_{ud}$. This extraction serves as a precise test of CKM unitarity and a sensitive low-energy probe for physics beyond the Standard Model (BSM).
