Dr. Dan Xie is currently an associate professor and doctoral supervisor at the School of Integrated Circuits in Tsinghua University. Dan Xie received PhD degree in Department of Microelectronics and Solid-electronics from University of Electronic Science and Technology of China in 2001. From 2001/09 to 2003/07, she joined Department of Materials Science and Engineering, Tsinghua University as a postdoctoral fellow working in the ferroelectric/dielectric materials (thin films and ceramics) and Sol-Gel chemical. Since 2003/07, she worked in Institute of Microelectronics (School of Integrated Circuits from 2021), Tsinghua University, mainly engaged in the research of novel micro-nano-electronic devices. In recent years, she has successively participated in and undertaken the research work of The National Key Research and Development Program of China, National Natural Science Foundation of China, National High-tech R&D Program of China (863 Program), Projects of International Cooperation and Exchanges NSFC and Projects commissioned by Enterprises and Institutions. She has rich research experience in the growth and characterization of two-dimensional thin film materials, the design and preparation of high-performance devices, and the functional implementation of flexible micro/nano electronic devices. She has published over 200 SCI papers in domestic and foreign academic journals and conferences such as Nature Nanotechnology, Nature Communications, Advanced Materials, Advanced Functional Materials, and ACS Nano, and obtained over 20 national invention patents. She was rewarded the 10th Young teachers awarded by Fok Ying Tung Education Foundation, winner of “The Program for New Century Excellent Talents in University of the Education Ministry of P. R. China”, and the "Academic Newcomer Award" of Tsinghua University.
