Graduate Student, University of Illinois at Urbana-Champaign
Undergraduate Student, Tsinghua UniversityHi, there! I'm Zhe Wang, a second year M.S. student at University of Illinois at Urbana-Champaign, majoring in Computer Science. I am advised by Prof. Lingming Zhang. Before coming to UIUC, I completed my undergraduate study at Tsinghua University, majoring in Mathematics and Physics.
Research Interests
My research interest lies in the intersection of Artificial Intelligence and Software Engineering. More specifically:
- LLMs for Code: to develop LLMs to solve software engineering tasks through post-training via synthetic data [Magicoder]
- LLM Applications: to empower LLMs with reasoning, planning and collaboration capabilities through alignment training [PurpCode] and agent-based systems [MultiAgentBench]
- Trustworthy LLMs: to enhance trustworthiness, resilience and reliability of helpful-only LLMs against vulnerable code and malicious cyberactivity attacks [PurpCode]
I am currently seeking for an Ph.D. position starting from Fall 2026. Feel free to drop me an email if you are interested in my research or have any questions. Please find my detailed Curriculum Vitae below:

PurpCode: Reasoning for Safer Code Generation

We introduce PurpCode, the first post-training recipe for training safe code reasoning models towards generating secure code and defending against malicious cyberactivities. PurpCode trains a reasoning model in two stages: (i) Rule Learning, which explicitly teaches the model to reference cybersafety rules to generate vulnerability-free code and to avoid facilitating malicious cyberactivities; and (ii) Reinforcement Learning, which optimizes model safety and preserves model utility through diverse, multi-objective reward mechanisms.

In this paper, we introduce MultiAgentBench, a comprehensive benchmark designed to evaluate LLM-based multi-agent systems across diverse, interactive scenarios. Our framework measures not only task completion but also the quality of collaboration and competition using novel, milestone-based key performance indicators.

Magicoder: Empowering Code Generation with OSS-Instruct
Yuxiang Wei, Zhe Wang, Jiawei Liu, Yifeng Ding, Lingming Zhang
ICML 2024
In this paper, we introduce Magicoder, a series of fully open-source (code, weights, and data) Large Language Models (LLMs) for code that significantly closes the gap with top code models while having no more than 7B parameters.
