杨杰， 2010年6月本科毕业于南京大学物理系（导师：祝世宁院士），2016年5月博士毕业于美国内布拉斯加大学林肯分校物理与天文系（导师：Martin Centurion教授）。2016年6月加入美国SLAC国家加速器实验室工作，担任实验研究助理（Experimental Research Associate），2018年11月升职为副研究员（Associate Staff Scientist），2020年6月升职为研究员（Staff Scientist）。主要科研成就包括：1）首次证实了兆电子伏电子束可应用于气态分子的衍射成像，并实现原子级时间（100飞秒）、空间（0.5埃）分辨率；2）发展了利用兆电子伏超快电子衍射（MeV-UED）拍摄气相“分子电影”的实验范式，并应用该方法成功捕捉非绝热过程；3）提出并证实了利用弹性与非弹性电子散射同时观测原子核、电子的超快动力学过程；4）搭建首台针对液相样品的超快电子衍射实验平台，并利用它捕捉到了纯水中氢键网络的“量子拖拽（quantum tug）”现象。

2021年3月全职回国，加入清华大学化学系基础分子科学中心。杨杰课题组致力于通过发展最前沿的科学仪器与实验方法学，促进人们对非平衡态分子动力学的深层次理解。主要研究方向包括：1）通过MeV-UED捕捉气相小分子的非绝热动力学过程；2）发展基于MeV-UED的液相样品原子级时空分辨探针，并利用它捕捉溶剂、溶质内的非平衡态结构动力学过程；3）发展基于四波混频或高次谐波的、针对气相有机小分子激发态的时间分辨光电子能谱装置。
