I am broadly working on aspects of Social Computing and Artificial Intelligence. The main aim of my research is to investigate and apply AI techniques to explore social behaviours, social relations, and communications. Most AI-driven systems consist of multiple decision-making entities, i.e., agents, who interact in a shared environment. These entities could be AI programs, smart sensors, or human users. When we design AI solutions, we need a deep understanding of how multiple agents should function in the shared environment, how they interact and communicate, and how behaviours of individual shape the collective outcome. My research revolves around the following directions:

1. Multi-agent Systems: We employ game theory and reinforcement learning to discover rewards or strategies of individuals, and how individuals' strategies impact others, thereby designing rules that elicit desirable behaviours and collective outcomes.

2. Social Networks and Graph Learning: Social network analysis studies the network topology of large and complex networks such as social ties among online users, and explores the structural features and dynamics of these network using game theory and representation learning technqiues.

3. Natural Language Processing: We employ neural-based natural language processing to extract semantic features of texts thereby enhancing understanding/generation of natural language texts for a range of application domains.

I am looking for capable project/thesis students who are interested in the topics above.
