Yibo Zhu

I am a Director at ByteDance AML (Applied Machine Learning), overseeing the R&D of machine learning systems. Before I joined ByteDance in 2018, I was a Senior Researcher at Microsoft Research, Redmond.

My interests include distributed systems and networks. I enjoy building large-scale software systems with emerging hardware like RDMA NICs, GPUs and programmable ASICs.

I obtained my Ph.D. from the Department of Computer Science at UCSB, co-advised by Prof. Ben Y. Zhao and Prof. Heather Zheng. I received my bachelor degree from Tsinghua University.

I am a recipient of Microsoft Research Ph.D. Fellowship (2015).

Selected service: TPC for ATC'22, SIGCOMM'21, SIGCOMM'20, SIGCOMM'18, CoNEXT'18. TPC Chair for KBNets'18. General Chair for HotNets'18.
