About - Nikolaos Pantelaios

AI Research Scientist — Meta

Hi, I’m Nikolaos (Nikos) Pantelaios. I’m an AI Research Scientist at Meta, working on post-training for Muse and the Muse Spark model family — RL and post-training for frontier models.

Before Meta, I did my PhD in Computer Science at NC State University (2018–2024), advised by Alexandros Kapravelos. My research was in web and supply chain security, applying AI to problems like JavaScript engine analysis and fuzzing (FV8), malicious npm package detection, and evasion techniques.

I’m originally from Greece and now based in New York.

Research interests:

• Post-training & RL for LLMs
• Generative AI
• Natural Language Processing
• Web & Supply Chain Security
• User Privacy

Thanks for reading!
