My interests revolve around understanding how intelligent agents build models (implicitly or explicitly) of the world around them and understanding the role language plays in this process. Somewhat more concretely, I am interested in:
- How agents model what other are agents are thinking (i.e., the use of "theory-of-mind" faculties), and how these models impact discourse.
- How natural language utterances are parsed into "executable" logical forms, and, more specifically, what role pragmatic inference (based upon contextual knowledge) plays in this process.
- How agents model the world dynamics (e.g., physics) of their environment (for use in control/reinforcement-learning), and how much of this modelling is implicit (cf. "model-free" RL) vs explicit (cf. "model-based" RL).
