Research Interests
- Adversarial robustness of advanced AI systems — Retrieval-Augmented Generation, agent communication protocols (MCP, A2A), and autonomous-agent trust boundaries.
- Trust-boundary security analysis for autonomous AI agents, with emphasis on the shift from output safety to behavioral safety.
- Large language models for cybersecurity — binary analysis, reverse engineering, and code similarity detection.
- Agent-driven C-to-Rust transpilation: autonomous coding agents that translate legacy C into idiomatic, memory-safe Rust while preserving behavior.
- Defenses against data poisoning and prompt injection: lightweight post-retrieval filtering for RAG and runtime guards for tool-calling agents.
