Experience

  1. Associate Research Fellow

    IHEP-CAS (Beijing)
    • Responsible for solar neutrino physics. Currently focus on developing machine learning based directionality aimed at improving the signal-to-background ratio.
    • Responsible for physics R&D for a new time projection chamber detector aimed at measuring low energy reactor neutrino spectrum.
  2. Postdoc Research Associate

    Princeton University (Princeton)
    • Responsible for developing analysis strategy for measurement of CNO solar neutrinos using Borexino Phase-III data.
    • Developed BAMBI method which improved sensitivity of Borexino to CNO from 2$\sigma$ to 5$\sigma$.

Education

  1. PhD in Astro-particle Physics

    GSSI (L'Aquila) and SISSA (Trieste)
    High precision spectroscopy of solar neutrinos with Borexino and JUNO. For Borexino, I developed a GPU fitter and made core contribution to the Borexino Phase-II pp-chain solar neutrino measurements. For JUNO, I proposed the TFC method which helps JUNO to reach 2 MeV threshold for $^8$B solar neutrinos.
