PhD student @ HKU, advised by Prof. Yiming Qiu. MSc CS @ HUST (adv. Prof. Qiang Cao) · BSc CS @ SYSU (adv. Prof. Yuedong Yang).
Research: optimizing ML systems and HPC — CUDA, DGL, sparse matrix acceleration. Explored sparse ops in ad-ranking systems at Tencent.
Outside academia: economics and investment.
I'm also building Chrono, a cross-platform time-tracking app for Web, Android, and macOS that records each day's time flow and tracks goal investment.
