01 / ABOUT ME

About me关于我

A foundation in engineering, with a growing interest in sustainable energy.以电气工程为基础，持续探索新能源与电力系统。

Learning by making
ideas work.让知识在实践中
得到验证。

I study Electrical Engineering and Automation at the Chongqing University–University of Cincinnati Joint Co-op Institute. My interests lie in renewable energy integration, microgrid optimization, and engineering simulation.我就读于重庆大学—辛辛那提大学联合学院电气工程及其自动化专业，关注新能源接入、微电网优化与工程仿真。

Across three Co-op terms, I have designed and assembled flexible LED circuits, supported power-system research at Tsinghua Sichuan Energy Internet Research Institute, and worked as a teaching assistant while developing microgrid models. I value careful checking, clear documentation, and open communication with a team.三段 Co-op 实习中，我参与了柔性 LED 电路的设计与制作，在清华四川能源互联网研究院开展电力系统相关研究，并在担任课程助教的同时推进微电网建模。我重视细致核查、清晰记录和团队沟通。
