Our group works in three broad areas: Computer Vision, Behavioral Imaging, and Mobile Health (mHealth). Within vision, we are developing the paradigm of First Person Vision and addressing a variety of fundamental problems in segmentation, recognition, video analysis, and visual tracking. Our Behavioral Imaging work develops novel methods to objectively measure and analyze social and communicative behaviors, with a focus on developmental disorders such as autism. Our work in mHealth develops novel mobile vision methods for assessing behavior and quantifying visual exposure. We are also developing predictive analytic methods based on machine learning for predicting future states of health risk from on-body sensor data.
