Wang Tuowei「王 拓为」 Hello! I am a second-year Ph.D. student in the Department of Computer Science and Technology at Tsinghua University, advised by associate professor Ju Ren. I hold dual B.S. degrees in Computer Science and Finance, both from Tsinghua University. My research interests include high-performance computing, machine learning system, and large-scale AI4Science system. Feel free to contact me if you have any questions, want to discuss research ideas, or just talk about... life. My Email: wtw23 [AT] mails.tsinghua.edu.cn |
