2006年在中科院物理所获博士学位。
2014.11-2017.2年在美国休斯顿大学物理系做访问研究。
主要研究方向：
电子显微学、电子晶体学方法及其在功能材料中的应用
热电材料原子尺度精细结构与物性研究
过去的主要工作及获得的成果：
主要研究方向电子显微学、电子晶体学及图像处理方法，及其在功能材料中的应用研究。近五年取得的主要结果分为两个部分，一部分为电子显微学方法研究，另一部分为在功能材料中的应用研究。主要包括：
利用电子晶体学方法（电子衍射结合高分辨电子显微像）将显微像的分辨率扩展到电子衍射的分辨率，基于普通电子显微镜图像，成功解析了一系列材料的晶体结构，并揭示了一些物理现象的起源。包括解析轻原子在内的氧化物晶体结构；分辨率可达1Å；确定半导体材料中缺陷核心原子构型；揭示LaCaMnO体系中电荷有序的起源。
结合透射交叉系数（TCC）理论和赝弱相位物体近似（PWPOA）理论对衍射图（高分辨像强度的傅里叶变换）中包含的非线性信息进行了研究。提出了一种分离球差矫正像中线性和非线性信息的方法，研究了非线性信息对球差矫正高分辨像的衍射图及解卷处理产生的影响。该结果对于更好地理解非线性信息对成像产生的影响以及如何合理利用非线性信息提高像的分辨率具有积极意义。
用球差矫正电子显微镜，在原子尺度揭示掺杂诱导的Zintl相热电材料的结构演变过程，研究新相结构及新物性。 确定了Eu2ZnSb2相的独特晶体结构和晶体中大量存在的面缺陷类型。分析认为大量分布的反相畴和本征的复杂结构是导致材料极低热导的主要因素。
