Biography
Welcome! I'm Van Tran, a 5th-year Ph.D. candidate at the University of Chicago working with Prof. Nick Feamster. What drives me is a deep commitment to protecting consumer privacy and making businesses more secure. I believe privacy shouldn't be a luxury—it should be built into the fabric of the internet. My work focuses on creating scalable, practical solutions that safeguard personal data while empowering businesses to thrive securely.
Research Interest
My research is driven by a mission to enhance online safety and privacy for internet users globally using ML/AI. I focus on application of machine learning for internet privacy, cybersecurity, and privacy law, including:
- Large-scale, automated analysis of websites’ compliance with the California Consumer Privacy Act (CCPA), including dark pattern detection.
- Detection of censorship on a large scale through machine learning.
- Efficient, privacy-preserving data acquisition from private data owners.
- Detection and generation of enterprise phishing emails using large language models (LLMs).
