My work focuses on the development of educational supplements that harness the power of ubiquitous computing technologies and physiological sensing. In particular, I study confidence estimation and readiness identification through numerous sensing technologies. My work is aimed at developing personalized learning tools which are accessible to all potential users. Research is primarily performed as in-the-wild studies. 

Currently, I lead a research group which is using the Oura Ring to study the sleep and activity behavior of approximately 100 participants for an extended period of time. The current goal is to develop appropriate supplementary tasks which can help us build ground-truth data for individuals. We are also studying the relationship between the devices and the participants as they are used in-the-wild. 

In addition, I also collaborate on a project which involves development of a new crowdsourcing technique which leverages confidence estimation to optimize task selection. The goal in this case is to use physiological sensing (eye-tracking) to quickly determine if a certain task is a good fit for a worker's abilities, thus reducing the risk of non-payment for poor performance.
