<h2>About me</h2>
<p>
I received the M.S. degree from Tsinghua University, in 2022 and the B.S. degree from Dalian University of Technology, in 2019.<br />
I am a core contributor to <b><a href="https://github.com/PaddlePaddle/Paddle">PaddlePaddle</a></b>, Baidu's open source deep learning platform. Since joining Baidu, I have become the <b><a href="https://github.com/PaddlePaddle/Paddle/graphs/contributors?from=2022-07-17&to=2023-10-01&type=c">top contributor</a></b> to PaddlePaddle on GitHub.
My research focuses on AI for System, including topics like AI compilers, reinforcement learning, and deep learning frameworks. My goal is to advance deep learning by making it more accessible, efficient, and applicable to real-world problems. Through my work on PaddlePaddle, I strive to create innovations that democratize AI and unlock its benefits for all.
