Xuewen Fu is currently a professor of condensed matter physics in School of Physics at Nankai University. He obtained his Ph.D. in Condensed Matter Physics from at Peking University in 2014 and joined in Prof. Ahmed Zewail (Nobel laureate) group in California Institute of Technology as a postdoctoral fellow to work on ultrafast electron microscopy (UEM), where he developed the first liquid-phase UEM, extending the dynamical studies with UEM to liquids. In June 2017, he joined in Brookhaven National Laboratory as a Research Associate and developed the first laser-free UEM with Prof. Yimei Zhu in 2019. In November 2019, he joined in Nankai University as a professor and built up the Nankai University Ultrafast Electron Microscopy Laboratory in 2020. Prof. Fu has published more than 60 journal papers, including one Science, three Science Advances, one Nature Communications, one Advanced Materials, and six ACS Nano etc. Prof. Fu’s research interest mainly focuses on the field of developing advanced in situ four-dimensional UEM and ultrafast optical spectroscopy technologies with high spatiotemporal resolution to study the transient structural, energy carrier and spin dynamics in low dimensional functional materials.
