About

I am broadly interested in the factors that promote or diminish happiness and well-being. My research program explores how constant connectivity to the Internet impacts people’s relationships and well-being and how we can harness technology to improve well-being and promote positive behavioral change. I am a Vanier Scholar and a Rising Star of the Association for Psychological Science (APS). I have written for *The* *New York Times*, *The Conversation*, and *Psychology Today*, and my work has been covered by other prestigious publications such as *The* *Economist, BBC, NPR, Forbes, Fast Company, Time Magazine, The Wall Stree Journal, National Geographic,* and *The Washington Post*. I have consulted for companies such as Ipsos, Canvas8, and Luce Research. See more at www.kushlev.com
