I work on systems security — attack mitigation, vulnerability finding, and confidential computing — spanning kernels, browsers, and trusted hardware. My recent focus is AI agent security: studying realistic attacks on LLM-based agents, such as prompt and data injection, and building principled defenses against them. More on our research →
