Research

I newly joined (Feb. 2021) the Jiangmen Underground Neutrino Observatory (JUNO)Link opens in a new window in China. This 20-kt liquid scintillator detector is currently being built and will be the flagship particle physics experiment in China for the next 30 years. With the JUNO collaborators, especially in close collaboration with students and young researchers from the Institute of High Energy Physics (IHEP) and the University of Chinese Academy of Sciences (UCAS), I am exploring the fascinating physics opportunities with neutrinos in JUNO.

For the Deep Underground Neutrino Experiment (DUNE)Link opens in a new window in the US, my group is analysing the data from ProtoDUNE at CERN, the prototype detector of the DUNE liquid argon (LAr) Far Detector. With the positively charged pion beams, we not only can demonstrate the state-of-the-art LAr technology but also aim to extract the intranuclear dynamics inside the argon nuclei that are crucial for the future neutrino oscillation programs at DUNE. To study these nuclear effects in LAr detectors with a neutrino beam, I am measuring TKI (see below) with collaborators in the MicroBooNE experimentLink opens in a new window.

My group is also working on the development of a high-pressure TPC for the DUNE Near Detector, in particular on a new design that can allow optimal neutrino-hydrogen measurements [Phys. Rev. D 102, 033005 (2020)Link opens in a new window]. This hydrogen-rich high-pressure TPC R&D is part of the EU AIDAinnova ProjectLink opens in a new window.

In 2016, I built the MINERvA-Oxford GroupLink opens in a new window which is now being moved to Warwick. In addition to leading the TKI measurements, my group works on the first BSM search at MINERvA. Recently, as Analysis Co-Coordinator of the experiment, I contribute to defining the analysis plan of the collaboration.

I joined the T2K ExperimentLink opens in a new window when I switched from the heavy-ion field. In 2015, I launched the TKI program in T2K. Recently, as Chair of the Analysis Proposal Committee of the Cross Section Group in the experiment, I help define and prepare new cross-section measurements.

One highlight of my research is the idea of using transverse kinematic imbalance [Phys. Rev. D 92, 051302 (2015)Link opens in a new window, Phys. Rev. C 94, 015503 (2016)Link opens in a new window], or TKI, to precisely identify intranuclear dynamics, or the absence thereof, in neutrino-nucleus interactions—an analogue of the missing energyLink opens in a new window technique used in collider experiments. I have been introducing this new technique to T2K, MINERvA, DUNE, and MicroBooNE to pursue an in-depth understanding of the nature of neutrinos.

Past activities

Collaborations

I enjoy working with research students at different stages, as well as with summer interns from across the world. I created the VISOSLink opens in a new window project for undergraduate research on neutrino oscillation phenomena.
