Nguyen Phong Hoang

Postdoctoral Researcher

University of Chicago

Thank you for visiting my homepage. I am a Postdoctoral Scholar in the Department of Computer Science at University of Chicago, working with Professor Nick Feamster.

My research interests are in the general areas of network security, online privacy, and Internet measurement. Specifically, by designing new systems and techniques to collect large-scale and longitudinal datasets, my research aims to improve the security of networked systems and reinforce the privacy of our online communications. Recently, this research goal has led me to focus on designing novel methods to (1) monitor information controls at scale by building systems for global and longitudinal measurements, and (2) evaluate and improve the effectiveness of domain name encryption protocols which have been proposed to enhance user privacy, e.g., DNS over HTTPS, and Encrypted Client Hello in TLS.

I obtained my PhD from The State University of New York at Stony Brook under the supervision of Professor Michalis Polychronakis. With the support from the OTF’s Information Controls Fellowship during my PhD, I have also worked with several interdisciplinary groups, including The Citizen Lab at University of Toronto and the networking research group of Professor Phillipa Gill at University of Massachusetts - Amherst.

While I have been writing and publishing research papers under the name Nguyen Phong Hoang (abbrv NP Hoang), my Vietnamese name is Hoàng Nguyên Phong {family name: Hoàng, given name: Nguyên Phong}. So for the ease of pronunciation, I often go by Phong or フォン if you speak 日本語 (I spent the best six years of my youth in Japan at 京都大学, JAIST, 立命館 APU).

I am serving on the program committees of IMC 2024, FOCI 2024, PAM 2024, PETS 2024, and USENIX Security 2024. Please consider submitting your work!
