Passive sensing of user behavior and Well-being at home
Learning people's behavior in their homes is central to health sensing, behavioral research, and building smarter environments. In this thesis, we explore learning such information in a passive and contactless manner - without asking people to wear sensors on their bodies or change the way they …

Comparing user behavior when targeted based on firm inferred interest vs. user stated interest
There has been a lot of discussions on giving user more control over their private information. Our paper wants to show how practices that give user more control over privacy, could facilitate collection of self-stated interest from voluntary users. This might potentially help firms to better …
