Formal methods X Agentic AI for Reliable Programming System

I am Dongjae Lee, a Ph.D. student in the School of Computing at KAIST and a member of Prosys Lab, advised by Kihong Heo.

Research Directions

Current questions I am actively exploring.

  • Proof-Carrying Spec-Driven Development. I want coding assistants to verify their own code and reduce the amount of human supervision needed for trustworthy software.
  • Mixing Natural and Formal Languages. I am interested in programming models that combine LLM-friendly natural language with analyzable formal structure.
  • Security for Agentic Software. My work explores how to analyze and secure agentic systems that execute tasks through prompts, tools, and autonomous workflows.
