Xiao Chen is an associate professor at the Department of Chemical Engineering, Tsinghua University, whose research interests focus on the development of low-dose atomic-scale imaging methods for porous materials, and is dedicated to single-molecule imaging in molecular sieves as well as direct observation of host-guest interactions, with a view to understanding and exploring molecular entry/exit mechanisms and the behavior of the interactions between the guest molecules and the host skeleton in the process of these chemical reactions from the molecular level or even the atomic level. She has published more than 60 articles, among which 12 are co-authored/corresponding authors, including Nature (3), Science (1), Nat. Commun. (5). The work of "A single molecule van der Waals compass" (Nature. 592, 541(2021)) was selected as one of the "Top 10 Scientific and Technological Progresses in Chinese Higher Education Institutions" in 2021, and she was awarded the Third China Molecular Sieve Rookie Award, the Young Chemistry Award of the Chinese Chemical Society in 2022, and was selected as one of the "Top 35 Scientific and Technological Innovators under 35 " in China in 2022. She has undertaken the projects of Excellent Young Scientist Fund of the Foundation Committee of China, the Facial Project, the Youth Fund Project, and the Key Research Subproject of the Ministry of Science and Technology. She is interested in the following three directions：

1.Ultrahigh spatial resolution imaging of porous materials by STEM, including zeolites and MOFs

2.Atomic single-molecule imaging to study various interactions and behaviors under nanoconfinement conditions

3.In situ imaging to reveal the dynamic single-molecule behaviors in the real applications
