Hao Cui 崔 灏

I am a 3rd-year Ph.D. student in the Networked Systems program at UC Irvine. My advisor is Prof. Athina Markopoulou. I am a member of the UCI Networking Group and ProperData Project.
My research is about auditing data collection practices of applications across various ecosystems (e.g. mobile, VR and web), with a focus on analyzing privacy policies at scale using natural language processing (NLP) techniques.
