Dr. Jiacheng Zhao is an Associate Professor and Master Advisor at State Key Lab of Processors, Institute of Computing Technology, Chinese Academy of Sciences (SKLP, ICT-CAS). I obtained my Ph.D. degree in July 2017 in ICT, CAS under the supervision of Professor Feng Xiaobing. I received my bachelor’s degree in computer science from Tianjin University in 2012.

Recently, my research focuses on building next-gen compiler infrastructure for domain specific accelerators, e.g. GPUs, AI Chips and network processors.

I’m looking for self-motivated students (Ph.D., M.S. and/or undergraduate students) to collaborate with me in the general area of compilers ranging from heterogeneous compiler construction and machine learning systems, to compiler assisted runtime systems. Send me an email if you are interested.
