研究领域
我是一名实验物理学者，正在围绕中国锦屏地下实验室的中微子实验开展研究工作。同时，我参与到 XMASS，SK，JUNO 等国际合作实验。这些实验都（将）位于地下实验室，地下环境为观测中微子和（可能的）暗物质提供了天然宇宙线屏蔽，是观测弱信号的基本条件。这些微弱信号中蕴含着物理学的前沿，包括可能平时被忽略的新粒子和新型相互作用。
在地下粒子物理的实验研究中，我的精力集中在大型液体探测器。它们有共同的探测原理，即液体与粒子相互作用发光，光子信号由液体容器边界上的光电倍增管等收集。光电倍增管是可以将单个光子转换成宏观电压脉冲的真空电子管器件。在粒子探测的实验技术中，我对新光子读出方法，现代统计学方法，大数据方法和高性能计算尤其感兴趣。
