Jingke Xu received his PhD from Princeton University, where he worked on the Borexino solar neutrino experiment and the DarkSide dark matter experiment for his dissertation. After receiving his PhD, he worked as a postdoc on the Sodium-Iodide with Active Background Rejection (SABRE) NaI(Tl) dark matter experiment to test the longstanding DAMA dark matter claim. At LLNL, Xu works in the Rare Event Detection Group on the LUX/LZ dark matter experiments and on the development of noble liquid technology for more sensitive dark matter and neutrino detections.
Xu’s research focuses on the detection of rare events, including the search for dark matter particles and the detection of low-energy neutrino interactions.
