I am tenure-track Faculty at CMU Language Technology Institute where I lead the Multimodal Communication and Machine Learning Laboratory (MultiComp Lab). I was previously Research Faculty at USC Computer Science Department.

My research focuses on building the computational foundations to enable computers with the abilities to analyze, recognize and predict subtle human communicative behaviors during social interactions. Central to this research effort is the technical challenge of multimodal machine learning: mathematical foundation to study heterogeneous multimodal data and the contingency often found between modalities. This multi-disciplinary research topic overlaps the fields of multimodal interaction, social psychology, computer vision, machine learning and artificial intelligence, and has many applications in areas as diverse as medicine, robotics and education.
