Yangruibo (Robin) Ding's Personal Website

Bio: I am an Assistant Professor in the Department of Computer Science at University of California, Los Angeles.

I completed my Ph.D. in Computer Science at Columbia University, advised by Prof. Baishakhi Ray and Prof. Gail Kaiser (an overview of my doctoral research can be found in this video). Previoulsy, I have also had wonderful experiences at Google DeepMind, AWS Agentic AI, and IBM Research.

Research: My research focuses on Large Language Models and Agentic AI for Software Engineering. Most recently, I am interested in building efficient, collaborative, and trustworthy agentic systems for complex software engineering and cybersecurity tasks.

🎯 I am actively looking for students to join my research group @ UCLA CS. Solid coding skills and experiences in large language models pre-/post-training, agentic systems, program analysis and verification, or software security are strongly preferred.

🤝 If you are interested in working with me, drop me an email with (1) your CV and (2) a brief introduction of your research interests and background.
