Dr Jie Zhang 

Dr. Jie Zhang is a Lecturer in Computer Science at the University of Southampton. After working as a Research Associate at University of Oxford, he joined the Agents Interaction and Complexity Group at ECS Southampton in November 2016.

Research

Research interests

Dr Zhang's research situates at the interface between computer science and economics. He is interested in understanding and characterising the incentives of self-interested agents in competitive and cooperative environments. He analyses agents' decision-making process and aligns their incentives with the objectives of a system designer by analytical methods. Ultimately, to evaluate and improve system performance in their equilibrium stages, under the worst-case guarantees and beyond worst-case scenarios. 

Dr Zhang's research is partially supported by a Leverhulme Trust Research Project Grant (2021 -- 2024).
