I am currently a postdoctoral researcher in the Department of Computer Science and Technology, Tsinghua University.

My research lies at the intersection of computer vision and deep learning system. My research interests include on-device and edge intelligence, optimizations for resource-constrained devices, and computer vision.

Previously, I received my B.Sc., M.Sc., Ph.D. degrees all in computer science, from Central South University, China, in 2016, 2018 and 2023. I was a visiting scholar at HCS Lab, Seoul National University in 2022-2023. I also joined HEX group at Microsoft Research Asia(MSRA) from Sept. 2019 to Mar. 2020, and Institute for AI Industry Research(AIR), Tsinghua University from Aug. 2021 to Apr. 2022 as a research intern, respectively.

My resume is here. [Chinese version] / [English version]
