主要研究成果：

从事材料辐照损伤、热年代学及高压研究工作。在辐照损伤和热年代学交叉方向的系统研究被裂变径迹领域权威Andrew Gleadow院士评价为“对基本径迹结构理解的非常重大进展”，“代表了这种背景下的巨大进步”。通过钻石刀制备透射电镜样品，观察到未腐蚀裂变径迹整个长度上每一点的辐照损伤及热退火情况，被EPSL审稿人Trevor Dumitru博士署名评价为“标定应用广泛的‘裂变径迹热年代学’体系中的一个非常重要的技术突破”。截至2017年11月，发表学术论文30多篇，其中SCI索引论文29篇，专利1项。目前是Scientific Reports, Contributions to Mineralogy and Petrology, Physics and Chemistry of Minerals, Journal of Materials Chemistry, Applied Physics Letters等近20个国际期刊审稿人。　

主要学术贡献及创新点：

1.发现磷灰石和锆石裂变径迹的不同结构，为理解两种材料中诸多不同行为提供了新的线索，为Shuster等人的辐照损伤‘束缚’模型提供了有力支持。

2.观察到裂变径迹的退火动态过程，为揭示磷灰石和锆石不同的退火机理提供最“直接”证据。

3.观察到整个裂变径迹长度，并发现裂变径迹退火速度随裂变半径的减小而加快的现象，为今后退火模型指明了方向。

4.证实核径迹半径大小与晶体方位无关，为退火方位效应提供了解释。

5.通过原位离子辐照观察到、并定量分析了阿尔法粒子对已有辐照损伤的恢复效应，为热年代学模型考虑这一效应提供了依据。

研究方向

矿物辐照损伤在热年代学的应用，材料辐照效应，高压(DAC)
