Software security with a heavy focus on fuzzing and program analysis. Researcher at Ada Logics
Automating OSS-Fuzz integrations using an agentic approach to build generation: blog.oss-fuzz.com/posts/oss-fu...

Fuzzing at scale requires a solution for build script generation, and an LLM-based agentic approach looks promising for this. It too works well with OFG's harness gen capabilities 🤟
