Research Interests

I work on computer networks and systems. I lead the NetX Lab. Welcome to visit us!

Current Projects

  • Data center transport, including load balancing, congestion control, and scheduling for high-bandwidth (100G) low-RTT (20 us)

  • NFV frameworks, line-rate low-latency programmable packet processing with minimal resource footprint in a virtualized setting

  • ML/DA systems, machine learning and data analytics are important, but system and deployment support of ML/DA (resource allocation, scheduling) is often the bottleneck to real-world use

Prospective Students

[2017/8 RA] I have 2 RA openings now. Please see here for more information.

I am always looking for bright PhD students to work with me. See here for more information.

Top venues for networked systems

I maintain a list of top conferences/workshops for networked systems sorted by their usual deadlines.
