Houyu Zhou

I am Houyu Zhou, a postdoc in the Algorithmic Decision Theory (ADT) Group led by Haris Aziz and Toby Walsh at UNSW Sydney. Prior to this, I got my PhD in Computer Science at City University of Hong Kong (CityU), under the supervision of Minming Li. I received my BEng from Computer Elite Class, Shandong University (SDU) in June 2020. I also visited John Hopcroft Center for Computer Science, Shanghai Jiao Tong University, hosted by Biaoshuai Tao, from July-2023 to Jan-2024.

I am interested in algorithmic mechanism design and computational social choice, especially facility location games, fair allocation, and multiwinner approval voting.
