Personal Information
I am a first-year PhD student currently investigating IPv6 scanning on the Internet. I previously also worked on Internet measurements pertaining to various protocols such as TLS, DNS, and QUIC during my undergrad and master's studies.
In my free time, my hobbies include long-distance running, making music, reading (especially philosophy), cooking, and bouldering with my fellow PhD students.
