代表性工作：
1.主持山东高等技术研究院AMS数据中心建设
作为项目负责人，主持建设山东高等技术研究院AMS数据中心。山东省和济南市投入专项财政资金7200万元。2020年1月启动建设，7月份建成，规模为15000物理核心、3 PB可用存储、1Gb/s国际网络，成为AMS实验的主要数据处理和计算中心。相关工作获山东省委表彰。
2.研究宇宙线电子和正电子流强的时间演化
作为分析工作的核心人员和协调人，完成了横跨11年的宇宙线电子和正电子每天流强的测量，以高显著度揭示了电子-质子、电子-正电子的太阳调制“时滞效应”(Hysteresis)，分析了长期和短期太阳调制效应与电荷符号、粒子质量的相关性。论文发表在PRL，入选PRL“编辑推荐”，《Physics》杂志专题评论。
3.研究宇宙线正电子和电子的起源
作为分析工作的核心人员和协调人， 基于1060亿个宇宙线数据样本，完成了宇宙线正电子和电子的数据的分析工作。于2013年发现了宇宙线正电子比例的超出(PRL 110, 141102 (2013))；2019年揭示了宇宙线正电子( PRL 122(2019) 041102)和电子( PRL 122(2019) 101101 ) 具有完全不同起源。
4.精确测量宇宙线反质子流强和反质子-质子流强比
协调2个反质子分析组之一 。本人开发出基于决策树的电荷误判识别方法，显著地提高了高能量反质子的测量精度，从而得到了最精确的测量结果，并发表在PRL上。这一重要的实验结果( PRL 117, 091103 (2016) )改变了学界对宇宙线中基本带电粒子 (质子、电子、正电子和反质子)的认识。
5.开发基于电磁簇射三维模型的AMS电磁量能器重建和粒子识别新算法
通过对电子三维簇射形状的分析，构建了电磁簇射参数化模型，开发了全新的三维簇射重建算法。该算法充分发挥了AMS电磁量能器的三维测量能力，将TeV (=1012 eV) 能量范围的粒子识别能力提高了一个量级，对测量TeV能量的宇宙线电子和正电子具有决定性作用。这项工作发表在 NIM A869 110 (2017) 上，本人为通信作者。
6.对AMS测量宇宙线基本带电粒子的分析工作做出决定性的贡献
精确测量宇宙线基本带电粒子是AMS的首要研究课题。本人是这一课题分析组的核心人员，推动了AMS关于基本带电粒子的分析工作。所发展出的分析方法，充分发挥了AMS关键子探测器(包括穿越辐射探测器，径迹室和电磁量能器)在高能量时的精度和性能，在AMS合作组中得到了广泛的应用，主要研究方法和成果发表于AMS合作组综述论文Physics Reports 894(2021) 1-116。
