On Research Interests




My research area covers the communication and the reality of humans in general. I have been working on Cognitive Linguistics, Pragmatics and Communication Studies. In particular, the following questions have been my main concerns:
  • How can people communicate with each other using language?
  • How does people segementalise and (re)cognize the external world?
  • How can people live in the world with a sustainable sense of reality?

My current research focuses on human-computer interaction and human-robot communication from the cognitive point of view, including the user involvement of computer users, the communicative functions of multi-modal information, and the organization of discourse with coherent intention.
