My primary research interests are in Intensity Frontier programs. Currently I am working on the NOvA, DUNE and Super-Kamiokande neutrino experiments.
NOvA is a long-baseline accelerator-based neutrino oscillation experiment that is optimized for electron neutrino measurements. It uses the upgraded NuMI beam from Fermilab and measures electron-neutrino appearance and muon-neutrino disappearance at its Far Detector in Ash River, Minnesota. The NOvA experiment aims to resolve the neutrino mass hierarchy problem and to constrain the CP-violating phase.
DUNE is the next generation long-baseline experiment in the US which will decisively determine the mass hierarchy and CP violation. DUNE detectors are based on liquid argon time projection chamber (LArTPC) technology, which offers excellent spatial resolution, high neutrino detection efficiency and superb background rejection. DUNE’s prototype detectors protoDUNE-SP and protoDUNE-DP have been taking data at CERN since 2018 .
Super-Kamiokande is the large water Cherenkov detector in Japan. Physics topics of the Super-Kamiokande experiment includes solar neutrinos, supernova neutrinos, atmospheric neutrinos, man-made neutrinos and proton decays.
Current research topics in my group include neutrino oscillation analyses to solve for Mass Ordering and CP violation, neutrino-electron elastic scattering measurements to constrain neutrino fluxes, deep learning based neutrino reconstruction technology at DUNE and NOvA, statistical tools in neutrino data analysis, R&D and fabrication of DUNE's liquid argon purity monitors (miniature time projection chambers measuring electron lifetime with deep UV in liquid argon), and calibration and data analysis of DUNE's single phase prototype protoDUNE-SP. In addition to physics students and postdoc, my group has several students from UCI computer science and statistics departments who are working on deep-learning algorithms and the statistical tools for neutrino reconstruction and analysis.
Before joining UCI, I was also deeply involved in the very topical search for exotic-hadron states and other studies of charm and charmonium physics in collider experiments. I have been the lead researcher for several important analyses with the BESIII experiment in Beijing, including being the primary author of the recent Phys. Rev. Lett (and Editor's suggestion) presenting the discovery of a new four-quark candidate Zc(3900)^0.
