My research interests lie in the intersection of software-defined networking and programming languages, along with a dabbling of computation and complexity theory. Currently, I am trying to devise an equational theory for match-action tables and pipelines commonly used in packet-switching dataplanes. On the practical side, I have worked with software packet forwarders in the realms of P4 and Vector Packet Processing (VPP) / fd.io.

At Cornell I am advised by Prof. Dexter Kozen, whom I have much to thank for his multi-disciplinary approach to problems and wide research interests. I also appreciate Profs. Nate Foster and Cynthia Farina serving on my committee.

My other academic interest outside Computer Science is Law, which I take as my minor subject in Cornell's CS Ph.D. program. This included a much-enjoyed brief opportunity to contribute some short legal research to Cornell Law School's Legal Information Institute.

Before Cornell, I completed my BA (MA 2016) and MEng in Computer Science at Emmanuel College, University of Cambridge, UK. I have many fond memories of Cambridge. Perhaps I will return someday!

Trivia

My Chinese surname "Long" 龙 is relatively uncommon.
I am a passable bridge player, although I only pass reluctantly.
I wish I could play flute more often. I wish I could play piano more competently.
One of my hobbies is reading court cases, as well as traveling. Reading court cases while traveling is perfect: either I will get through the journey in no time at all, or I will be unconscious throughout.
