Xin Zhang is an Assistant Professor at the Department of Computer Science and Technology, the School of Electronics Engineering and Computer Science, Peking University. While he is broadly interested in topics related to programming languages (PL) and software engineering (SE), his current focus is on program analysis and its interplay with machine learning (ML) and artificial intelligence (AI). On one hand, he leverages ideas from ML/AI to build better program analyses. On the other hand, he develops program analyses and languages for improving intepretability, fairness, robustness, and safety of ML/AI systems.
