About Me
I am a Research Engineer at Google DeepMind. I earned my B.Sc. degree from the Dept. of Earth and Space Science, Peking University in 07/2019. During my time in school, I worked as a research assistant at the Key Laboratory of Computational Linguistics at Peking University, advised by Prof. Xu Sun. I also spent some fun time interning at Big Data Mining Group, Microsoft Research Asia (2017-2018), and DiDi AI Labs (2018).
My current research is centered on large language models (LLMs) post-training, with a focus on improving their general reasoning abilities including math, science, coding and planning. Prior to the emergence of LLMs, my studies revolved around deep learning applications in the fields of natural language processing and computer vision. Additionally, I have been engaged in machine learning problems related to optimization algorithms and model compression.
