I am a senior researcher (Oberassistent) at ETH Zürich, where I have been part of the NetSec Group led by Prof. Adrian Perrig since mid 2021. I received my PhD (Supervisor: Prof. Cong Wang) and BSc (Honors, First Class) both from City University of Hong Kong.
My research currently revolves around the Domain Name System (DNS), a cornerstone of the Internet, along three interacting tracks: (1) analyzing and mitigating fundamental DoS vulnerabilities in DNS, (2) developing formal methods to rigorously reason about DNS protocols and implementations, and (3) designing a next-generation secure naming system for both today's and future Internet. I'm leading these projects as the PI or Co-PI of several research grants with a team of students and researchers.
I have explored, and am still interested in, various topics in applied crypto, confidential computing, and decentralized technologies.
