research


My research is in computer vision and multimodal (video-audio-language) learning. I aim to develop perceptual AI agents that can assist humans in their daily activities by understanding their behavior from video and communicating through language and actions. I am particularly motivated to apply this research to AI/AR coaching, episodic memory retrieval, and human-robot interaction.
