I am a computer scientist interested in the research and development of conversational machines that can talk, listen, see and move. The research and development of such kind of machines is challenging and interesting at the same time because they bring together several subfields within artificial intelligence. I am particularly interested in the innovation of conversational systems applied to information-seeking, situated and human-robot domains. My current research interest consists in investigating computational methods based on the reinforcement learning paradigm for building multilingual and multimodal dialogue systems exhibiting adaptive behaviour in unknown and uncertain environments. The goal behind these research interests is to understand how to build conversational systems that learn to optimize the tradeoffs derived from effective, efficient, flexible, non-monotonous and robust interaction in a wide-range of task-oriented scenarios.

 

RESEARCH INTERESTS:

 

Adaptive dialogue systems, spoken language processing, multimodal interaction, applied machine learning, intelligent robotics.
