First-authored papers have won the ICLR 2023 Outstanding Paper Award and ICLR 2024 Outstanding Paper Honorable Mention; Ph.D. thesis selected as CAAI Outstanding Doctoral Dissertation Honorable Mention and Outstanding Doctoral Dissertation in Peking University.
Research Experience
Research areas include understanding the power and limitations of large language models (LLMs) in complex reasoning; analyzing the expressive power of graph neural networks (GNNs), providing guidance on GNNs design principles that enable them to effectively represent necessary graph structural information; designing powerful Lipschitz neural networks with certified robustness guarantees; designing and analyzing optimization algorithms for efficient neural network training.
Education
Ph.D. student at Peking University, advised by Prof. Liwei Wang; Undergraduate studies at School of the Gifted Young in Xi’an Jiaotong University, majoring in Computer Science.
Background
Main research area includes studying the foundations of machine learning, such as the expressive power, robustness, and optimization of neural networks. Provides theoretical and algorithmic insights into the strengths and weaknesses of fundamental deep learning models and algorithms (often through a computer science perspective), based on which designs new (provably better) models/algorithms.
