About me
I research and build AI for cybersecurity. My work connects machine learning, language models, and security operations, with an emphasis on systems that can be evaluated and trusted in practice.
At Wiz (Google), I work on autonomous threat investigation, security assistants, and automated remediation. Earlier, at Cybereason, I developed machine learning for malware detection and static analysis, alongside LLM applications for security teams.
A recurring question in my work is simple: did we improve the system, or just move the metric? I’m interested in agent evaluation, reproducible investigations, and smaller models trained for specific security decisions.
