About Me

I am currently a postdoctoral researcher at the Dept. of Computer Science and Engineering, The Ohio State University. I'm fortunate to work with Wei-Lun Chao, Yu Su and Tanya Berger-Wolf. I obtained my Ph.D. in 2024 from College of Control Science and Engineering, Zhejiang University, Hangzhou, China. I was supervised by Wei Jiang. Previously, I received my B.Eng. in Zhejiang University in 2019. During Sep. 2022 - Oct. 2023, I was a visiting scholar at HPC AI Lab, National University of Singapore, under the supervision of Yang You.
