Graduate research focus

My graduate research at the NYU Osiris Lab explored the intersection of artificial intelligence and cybersecurity.

Adversarial Machine Learning & LLM Supply Chain Security

My research focused on understanding how adversarial techniques can compromise machine learning models, with particular emphasis on LLM supply chain vulnerabilities. The Package Hallucination Detection System serves as a foundational tool for identifying when LLMs suggest non-existent dependencies — a vector that could lead to supply chain attacks if malicious actors register these hallucinated package names.
