个人简介

      副研究员，1984 年生。2002 年本科毕业于北京大学物理学院物理学系，2011年毕业于中国科学院物理研究所，获得光学博士学位。2011-2016年在美国莱斯大学化学系从事博士后研究。现为中国科学院物理研究所软物质物理重点实验室副研究员。

目前主要研究方向

      进一步发展和建立多种领先的超快光谱技术，解析各类二维光电材料、纳米半导体光催化材料以及光合膜蛋白系统等多种光转换体系内的超快动力学过程，从微观上揭示光生载流子及激子的性质及传输机制，为提高其能量传递及电荷分离等效率提供科学依据。

过去主要工作及所获成果

      长期从事各种先进超快光谱仪器的研发及应用的研究工作，例如：发展光参量荧光放大飞秒时间分辨瞬态荧光光谱技术，并将其首次应用至光合模拟体系与海藻捕光蛋白的研究中；发展国际独有的多维振动光谱技术，使其成为解析各种体系内分子三维构象的常规手段，并兼具飞秒量级的时间分辨本领；深入阐述分子振动能量传递的机理，并有潜力将这一能量传递过程作为精度小于1埃的“分子尺”来测量分子间的距离；建立飞秒超宽谱带红外显微探测技术，并首次利用其研究二维材料以及其它多种光电材料内各类激子、自由载流子等的超快动力学过程，以此观察到二维材料异质结内超快电荷转移中间态的存在，并实现在超快时间尺度上对二维材料晶格温度的实时观测，揭示其中非辐射电子能量耗散通道，等等。目前，以第一/通讯作者在Nature Communications、ACS Nano、Chemical Science、International Reviews in Physical Chemistry等重要学术期刊上发表了近二十篇科研论文。
