A key challenge of data-driven social science is the gathering of high quality multi-dimensional datasets. A second challenge relates to design and execution of structured experimental interventions in-situ, in a way comparable to the reliability and intentionality of ex-situ laboratory experiments. In this paper we introduce the Friends and Family study,(More)
In recent years, reality mining experiments have provided several novel insights into human social behavior that would not have been possible without the novel use of smart phone sensing. In this work, we leverage the latest reality mining experiment to study social behavior from a public health perspective. In particular, we focus on sleep and mood as they(More)
The aim of this study is to understand the relationship between automatically captured social exposure and detailed sleep parameters of healthy young adults. This study was conducted in a real-world setting in a graduate-student housing community at a US university. Social exposure was measured using Bluetooth proximity sensing technology in mobile devices.(More)
Sleep and mood problems have a considerable public health impact with serious societal and significant financial effects. In this work, we study the relationship between these factors in the everyday life of healthy young adults. More importantly, we look at these factors from a social perspective, studying the impact that couples have on each other and the(More)

Abstract Studies have suggested that propinquity; social, cultural, physical and psychological similarities are major factors in close friendship ties. These studies were subject to human recall of interactions with no details of length or(More)
Research has mostly focused on obesity and not on processes of BMI change more generally, although these may be key factors that lead to obesity. Studies have suggested that obesity is affected by social ties. However these studies used survey based data collection techniques that may be biased toward select only close friends and relatives. In this study,(More)
Several studies have suggested that propinquity, social, physical and psychological similarities are the major social processes required for the evolution social ties. This study attempts to understand the effect of these social processes on the creation of social encounters at different lengths of interaction. Co-location and communication sensors in(More)
We live in a fast-paced busy world where one of the key biomedical factors we compensate with is sleep. Sleep impacts many facets of our lives from chronic disorders to workplace productivity, happiness and many other dimensions that we are continually discovering. Advances in technology and health informatics have made it possible to measure and understand(More)
