会议承办:上海光机所青年创新促进会小组光机所团委余平博士是密苏里大学物理和天文学系的副教授.
他毕业于南开大学,获得学士(1984)和硕士学位(1987年,师从张光寅教授),于1997年获得香港科技大学博士学位(师从Prof.
GeorgeKLWong).
他的研究结合了半导体光学,超快激光和生物医学光学成像.
余平博士最具代表性的研究成果为:(1)在ZnO外延薄膜和微观室温条件下受激发射,包括激射增益机制的开拓性工作(香港,1995年-1997年);(2)对理解极化和垂直耦合半导体量子点的电子态等研究工作的贡献(丹麦,1999年);(3)全息光学相干成像和荧光断层成像的创新性研究(美国普渡大学和密苏里大学).
他目前的研究项目包括光学相干断层扫描,全息光学相干成像,荧光介导的弥漫光子成像、量子光学以及半导体和聚合物设备等领域.
他正从事的生物医学成像技术研究在临床预诊和临床成像应用等领域中具有巨大的潜力.
