Background


About Me

I earned my Master's degree from Southwest Jiaotong University in 2024, where my research focused on smart construction safety management. Currently, I am a PhD student at the City University of Hong Kong, exploring innovative ways to integrate cutting-edge technologies into management and sustainable development.

My research interests include the following key areas:

  1. Harnessing Generative AI for Construction Management
  2. Applying Reinforcement Learning in Optimization and Decision-making
  3. AI-Empowered Smart Operations and Maintenance of Infrastructure
  4. Big Data Mining for Sustainable Urban Research

Outside of academics, I enjoy an active lifestyle. My hobbies include playing table tennis and badminton, hiking through scenic trails, and occasionally running. Additionally, I run an academic self-media account where I share my learning experiences and insights with a broader audience. Feel free to connect and exchange ideas with me!
