My research interests are in digital signal processing, speech and video processing, and multimodal interfaces. My current research includes modeling and understanding human communication and interaction, with applications to automated recognition and synthesis to enhance human-machine interfaces. I have worked on audio-visual emotion recognition, analysis of emotional modulation in gestures and speech, designing realistic human-like virtual characters, speech source detection using microphone arrays, speaker localization and identification in an intelligent environment, and sensing human interaction in multi-person meetings
