I was a winner of the 2018 Spence Award for Transformative Early Career Contributions from the Association for Psychological Science. It is a great honor to be recognized for my efforts to develop computational models for happiness and to study happiness in samples of tens of thousands of people using our smartphone app, The Great Brain Experiment. There is an interview with me in this month's APS Observer magazine. I am grateful to all of the support of my mentors and colleagues over the years. I hope that my lab's research will advance our understanding of how happiness works and help explain the symptoms of psychiatric disorders including major depression and bipolar disorder.
