主讲人简介:
欧阳鑫昊,2002年-2006年在四川农业大学生物技术专业学士。2006年-2011年在四川农业大学水稻研究所攻读博士学位。于2009-2011年被国家留学基金委公派到耶鲁大学邓兴旺教授实验室进行联合培养,主要从事拟南芥转录因子FHY3全基因组结合位点分析与FHY3调控叶绿体分裂的机制研究。2011回国后,留四川农业大学水稻研究所工作,从事水稻光周期调控水稻开花和穗发育相关工作至今。并于2012年初到北京大学邓兴旺教授实验室做在职博士后。博士后期间,一方面完成拟南芥FHY3在UV-B光信号下的调控机制,另一方面利用系统生物学的方法完成UV-B信号网络建模并分析各元件的协调工作机制。目前,主要致力于光信号在水稻生长发育中的作用机理研究。
