1997年8月在中国科学院物理研究所获理学博士学位。1997年至2005年先后在瑞典隆德大学(Lund University,Sweden),美国威廉-玛丽学院(The College of William & Mary, USA), 美国俄克拉荷马大学(University of Oklahoma, USA),以及加拿大蒙可顿大学(Unviersity of Moncton, Canada)做博士后与助理研究员工作。2006年1月到中科院半导体所超晶格国家重点实验室工作。
一直从事低维半导体纳米材料的线性与非线性红外激光光谱以及飞秒(皮秒)超快动力学光谱的实验研究工作。近年来着重于半导体自旋电子学及器件(Spintronics)领域的研究, 对磁性及非磁性半导体纳米材料在自旋电子器件领域的应用进行相关材料与物理的基础实验研究。
主要研究方向:
1)半导体量子结构中电子与自旋的超快激发与弛豫动力学过程及其调控的基础物理研究;
2)铁磁薄膜及其与半导体异质结微纳结构中集体自旋的超快激发与磁化动力学过程研究;
3)新型低维半导体量子结构的光学非线性响应研究。
