I work at Tencent AI Lab 
as a research scientist now in Shenzhen.
I graduated from Wuhan University (2017/09 - 2021/06) with a bachelor’s degree and from the Intelligent Interaction Group, SIGS @ Tsinghua University (2021/09 - 2024/06) with a master’s degree, advised by Prof. Yujiu Yang.
Research
I am generally interested in natural language processing and machine learning. Current interests include:
- Effective Model Architecture
- Efficient Training and Inference
- Mathematical Reasoning
