人物經歷
於1981年、1986年和1994年分別在中國科學技術大學物理系、中國科大物理系和中國科大國家同步輻射實驗室分別攻讀學士、碩士和博士學位，分別研究非晶合金的結構馳豫和超導性質及比熱、高溫超導材料的摻雜和物性研究、及利用同步輻射研究超導材料的電子結構等課題。並曾分別在北京大學技術物理系、英國的Leeds大學做博士後，研究鐵電材料在重離子輻照後其光折變回響速度的變化及其機理、新型非晶態磁性合金的性質及其電子結構，於2007年至2008年赴加拿大Saskatchewan大學做訪問學者，開展X射線吸收、X射線發射以及非彈性X射線散射等研究。曾經在英國Daresbury和美國Advanced Light Source、加拿大Canadian Light Source等國際上的同步輻射實驗室開展實驗研究。本人與國內多家研究單位具有良好的合作關係，如中國科學技術大學國家同步輻射實驗室、中國科學院高能物理研究所北京同步輻射實驗室、北京大學物理學院等；並與國際上一些單位有良好的合作關係，如英國的Leeds大學物理系、英國的Salford大學物理系、英國的Daresbury同步輻射實驗室等，加拿大Saskatchen大學和加拿大Canadian Light Source等。多年來一直從事材料的物性、電子結構和微結構的研究工作，並依此分析摻雜或離子輻照使材料改性（光折變回響速度提高）的機理，曾分別研究高溫超導和磁性多層膜的界面問題，同時還具有多年的同步輻射套用研究的經歷。
目前利用同步輻射開展龐磁電阻氧化物的原子結構和電子結構的研究，並曾與南京大學蔣樹聲教授合作研究納米介電薄膜；分別主持和參與國家自然科學基金項目多項；近年來已發表SCI論文三十餘篇，並有多篇論文被他人引用。
