About

I am a PhD student in Computer Science working on intelligent network security systems. My research explores how large language models can support the analysis and management of network access control policies. My most recent research in this context is on LLM confidence estimation and privacy and security of LLM-based chat bots.

I always love to chat about new ideas and collaborate on research! Don't hesitate to reach out to me via email if you are working in similar fields or research!
