个人简介

于1981年、1986年和1994年分别在中国科学技术大学物理系、中国科大物理系和中国科大国家同步辐射实验室分别攻读学士、硕士和博士学位，分别研究非晶合金的结构驰豫和超导性质及比热、高温超导材料的掺杂和物性研究、及利用同步辐射研究超导材料的电子结构等课题。并曾分别在北京大学技术物理系、英国的Leeds大学做博士后，研究铁电材料在重离子辐照后其光折变响应速度的变化及其机理、新型非晶态磁性合金的性质及其电子结构，于2007年至2008年赴加拿大Saskatchewan大学做访问学者，开展X射线吸收、X射线发射以及非弹性X射线散射等研究。曾经在英国Daresbury和美国Advanced Light Source、加拿大Canadian Light Source等国际上的同步辐射实验室开展实验研究。本人与国内多家研究单位具有良好的合作关系，如中国科学技术大学国家同步辐射实验室、中国科学院高能物理研究所北京同步辐射实验室、北京大学物理学院等；并与国际上一些单位有良好的合作关系，如英国的Leeds大学物理系、英国的Salford大学物理系、英国的Daresbury同步辐射实验室等，加拿大Saskatchen大学和加拿大Canadian Light Source等。多年来一直从事材料的物性、电子结构和微结构的研究工作，并依此分析掺杂或离子辐照使材料改性（光折变响应速度提高）的机理，曾分别研究高温超导材料、磁性多层膜的界面、庞磁电阻氧化物、多铁性材料等问题，同时还具有多年的同步辐射应用研究的经历。
