Research

My main research interests lie in the intersection between Ubiquitous Computing (Ubicomp) and Human-Computer Interaction (HCI). Specifically, I have been working on creating technologies to support mobile communication and attention,  mobile crowdsourced behavioral data collection, and city exploration. Recently, I'm also starting my research in human intelligence interaction and attention in VR.   I'm seeking collaborators and students who have the same interest.
