I am Ziyi Zhang, a second-year PhD student at University of Chicago, where I am advised by Prof. Hank Hoffmann. I am currently part of the Updown project, where we speed up graph analytics jobs using a novel architecture and new programming model.

I went to my undergrad at University of Wisconsin-Madison, where I majored in Computer Sciences and Mathematics. It is my pleasure to be advised by Prof. Shivaram Venkataraman on system research and by Prof. Dieter van Melkebeek on competitive programming.


Apr 22, 2024 My teammates and I won the 8th place and silver medal at 2023 (46th) ICPC World Finals at Luxor, Egypt! (Check out the school news (English) and my reflection (Chinese))
Apr 15, 2022 I am going to UChicago for my PhD this fall!
