Hi! I'm Alan (Zaoxing) Liu, currently a postdoc at Carnegie Mellon University working with Prof. Vyas Sekar (CMU) and Prof. Minlan Yu (Harvard). I obtained my Ph.D. in Computer Science from Johns Hopkins University, advised by Prof. Vladimir Braverman.
I'm broadly interested in systems and networking. Accordingly, I design, implement, evaluate systems and algorithmic tools for network telemetry, in-network computing, data analytics, and network security.
I'm on the academic job market. Please reach out if you think we may be a good fit :) Thanks! [Email]
