About Me
💻 I just graduated from Tsinghua University, with a Bachelor of Engineering and a Bachelor of Arts. And I was honored to have been a member of Yao class, directed by the Turing Award Laureate Andrew C. Yao. I studied Computer Science at Institute for Interdisciplinary Information Sciences and Chinese Language and Literature at School of Humanity. I am an incoming PhD student at University of Washington.
📚 My research interests are broad. During my undergraduate, I am fortunate to have worked with Prof. Simon S. Du at UW and Prof. Huazhe Xu at Tsinghua.
👽 My mind is open. If you have any ideas which we both might be interested in, feel free to reach out.
