Short Bio (full resume, 中文版): Born in China, B.Sc. from Macau (2006), Double M.Sc. from Germany & Spain (2009), Double PhD from Australia & France (2012), Postdoc working with Makoto Yokoo (Kyushu, Japan) (2013 - 2014) and Research Fellow working with Nick Jennings (Imperial, UK) (2014 - 2017), Assistant Professor at ShanghaiTech (Shanghai, China) (2017 -) and lead The ShanghaiTech Multi-Agent systems Research Team (SMART). Zhao was elected as a member of the IFAAMAS Board of Directors in 2022, the first representative from a Chinese institution since IFAAMAS was founded in 2002. He is a senior member of the China Computer Federation. He was program/track co-chair of DAI 2021, Workshop Track of PRICAI 2021, Competitions Track of IJCAI 2022, Sponsorship of PRICAI 2022, and Demo Track of AAMAS 2023.

Research:
  • Most of Zhao’s research is on algorithmic game theory and multi-agent systems, especially mechanism design and its applications on social networks. He pioneered and promoted a new trend of mechanism design on social networks, namely how to incentivize the existing participants of a game to invite new participants via their social connections. For this research challenge, Zhao’s group have made several seminal contributions in auctions, coalitional games and matching with over 20 high-quality papers. He has also contributed a blue sky paper at AAMAS 2021 to set up the related research agenda and offered four tutorials at AAAI 2022, AAMAS 2019 and IJCAI 2017/2018. He was invited to give an Early Career Spotlight talk at IJCAI-ECAI 2022.
