๐Ÿ‘‹ Welcome to My Personal Homepage

I am currently a Ph.D. candidate in the Department of Automation at Tsinghua University, working under the supervision of Prof. Xiao He and Prof. Donghua Zhou at the Research Center of Safety Control Technology.

Prior to this, I received my B.E. degree in Computer Science and Technology from Southwest University. During my undergraduate studies, I worked as a research assistant in the Laboratory of Information Fusion and Intelligent Science at the University of Electronic Science and Technology of China with Prof. Yong Deng.

My research focuses on online learning and its applications in real-time safety assessment, safety-guaranteed control, and multi-condition fault diagnosis of dynamic systems, such as robotic swarms, industrial automation systems, and safety-critical cyber-physical systems. My overarching goal is to enable reliable and safe operation for both large-scale industrial assets and small intelligent agents, even under complex and uncertain environments.

In recent years, I have been working to build a more complete theoretical and methodological framework for safety assessment and safety-guaranteed control in dynamic systems, and to extend it to a wider range of real-world applications. I am especially willing to share research resources whenever possible, including models, code, data, and survey materials, to support community exchange and reproducibility. In addition, I am interested in interdisciplinary applications. Since many natural processes can also be viewed as dynamic systems, I am interested in applying the advanced process monitoring technologies developed in this context to tackle critical challenges in environmental engineering, particularly in domains such as hydrology and atmospheric science.

I believe high-quality research often comes from open discussion and active idea exchange. If you are interested in any of these topics, feel free to contact me by email. I look forward to working together to help make the world safer and better :)
