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.
