The “Happy Tech” Team


The Digital Health and Happiness Lab (or Happy Tech Lab) is lead by Dr. Kostadin Kushlev at Georgetown’s Department of Psychology. Lying at the intersection between digital technology, happiness, and health, the research in The DHH Lab is designed to answer basic scientific questions about the role of digital technology in health and well-being with both theoretical and applied implications. Methodologically, our research aims to elucidate psychological processes as they occur in the field and people’s regular daily lives, thus relying heavily on monitoring behavior and health in real time and relying on large survey data and Big Data analysis, while employing advanced statistical approaches such as machine learning and multilevel modeling. Researchers in the lab also aim to develop interventions to increase happiness and improve health through targeted modifications to people’s digital behavior. Through these statistical and experimental approaches, the lab thus aims to elucidate the psychological processes behind human health, happiness, and flourishing in the modern digitized human environment. Below you can find some of the incredible students and graduates involved with the ongoing work of the lab!
