I am interested in socially intelligent AI. More specifically:

📢How do we build socially intelligent AI systems? e.g., Sotopia, Social World Models
🧱How do we create AI agents that effectively help humans? e.g., WebArena, TOM-SWE
🛡️How do we ensure AI systems behave safely and align with human values? e.g., HAICOSYSTEM, OpenAgentSafety
