He Ye | Assistant Professor at UCL

This is Ye! I am a Lecturer (equivalent to Assistant Professor) in the Department of Computer Science at University College London. My research in multimodal agentic coding focuses on making programming more efficient and accessible. Specifically, I work on large language models (LLMs) for code generation, test generation, and GitHub issue repair. Previously, I was a postdoctoral researcher at Carnegie Mellon University (2023-2025), where I worked with Prof. Claire Le Goues. I completed my Ph.D. at KTH Royal Institute of Technology, advised by Prof. Martin Monperrus and Prof. Benoit Baudry, and completed my B.S. degree from Sichuan University.

We are organizing the LMPL@SPLASH 2025 workshop and the APR@ICSE 2025 workshop, we look forward to your submissions!

Opportunities to Work Together

I am actively looking for self-motivated PhD students (fully funded, partially funded, or self-funded) to work on topics related to LLM4Code. If you are interested in working with me, please follow the steps below:

• 1) Apply to the CS Doctoral Programme before applying for any scholarships. Detailed application information is available here: https://www.ucl.ac.uk/computer-science/study/postgraduate-research/computer-science-mphilphd.

• 2) In your application, please list He Ye and Federica Sarro as potential supervisors, and select Software Systems Engineering (SSE) as your preferred research group.

• 3) Once you have submitted your application, please email me your CV and application number so that I can access your application and arrange an interview.

If you are a BSc or MSc student at UCL and interested in research within our group, feel free to email me to arrange a 15-minute meeting.
