教育经历

1997年毕业于武汉大学物理系，获得理学学士学位；在中国科学院半导体研究所，取得博士学位，曾在清华大学电子工程系从事博士后研究。


工作经历

2005年入职北京师范大学新器件实验室，研究新颖半导体探测器物理及相关技术。


         近十余年，新器件实验室（NDL）主要开展一种被称为硅光电倍增器（SiPM）的单光子探测器的研制，以及相关电子学和应用方面的研究工作。SiPM是一种由工作于雪崩击穿电压之上和具有雪崩淬灭机制的雪崩光电二极管阵列并联构成的，具有极佳的光子数分辨和单光子探测灵敏度的硅基弱光探测器。外延电阻淬灭型硅光电倍增器（EQR SiPM），具有结构紧凑、“死区”面积小、微单元密度高、探测效率高、动态范围大、响应速度快、雪崩电压随温度变化系数小以及性价比高等优点，已成为有代表性的SiPM器件结构之一，特别适合于核医学成像（PET、SPECT、光子计数型CT）、辐射探测与安检、荧光测量、光谱测量等弱光探测与传感领域，在粒子物理与核物理研究、核医学诊疗、激光雷达、荧光检测等领域有非常重要和广泛的应用。
