JWare Lab

JWare Lab (杰件实验室) is affiliated with the Department of Computer Science at Michigan Technological University. The name JWare is inspired by the PI’s first name, Jie (pronounced “jyeh”), a character meaning greatness. This reflects our aspiration: that software, built with the right foundations, can be truly great. We also aspire to empower students with the foundations to build great software in their future careers — in an era increasingly shaped by Generative AI.

We investigate the quality foundations, principles, and methodologies that make AI-assisted software engineering rigorous and trustworthy. Our research spans the full software development lifecycle: design, coding, testing, review, deployment, and maintenance. We are committed to ensuring that AI tools elevate the quality and safety of software, rather than erode it.

Join Us

🎓 Hiring PhD Position (Fall 2026): I am recruiting highly-motivated students to join my research group at Michigan Tech, a Carnegie R1 (Very High Research Activity) institution, to work at the intersection of Software Engineering and AI, particularly Large Language Models. See more details in this link. I apologize that I’m unable to reply to each email individually. A practical tip: the strongest applicants apply directly to the PhD program rather than waiting for my reply, and we talk once they stand out in the applicant pool.

📧 Hiring RA Position at MTU (Summer / Fall 2026): Paid Undergraduate/Graduate Research Opportunity available in Agentic Software Engineering for MTU students. If you are interested, please see this link.

See our open positions for full details on both.
