Develop programming models and machine learning-based task graph scheduling algorithms to accelerate scientific computing applications using modern C++, CUDA, and Pytorch

Short Biography
I earned my Ph.D., under the supervision of Prof. Tsung-Wei Huang, from the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison in August 2025, with a focus on parallel and heterogeneous computing and reinforcement learning-based scheduling algorithms using C++ and CUDA. During my Ph.D. career, I published 18 research papers (9 of them are first-authored). I received an honorable mention in the ACM ISPD Wafer-Scale Physics Modeling Contest 2021. I also presented at the leading C++ connference CppNow in 2023.
