I am a Research Scientist at Stanford University and the Director of the Psychological Science Accelerator. I conduct research in affective science, cross-cultural psychology, and meta-science.In affective science, I seek to understand the social, cognitive, and physiological processes that underlie emotion. Much of my research here has focused on the facial feedback hypothesis, the idea that sensorimotor feedback from facial expressions can impact emotional processes (e.g., that smiling can make people feel happy).In meta-science, I seek to build research infrastructure that allows researchers to obtain generalizable knowledge about psychological phenomenon. In this domain, I direct the Psychological Science Accelerator: a globally distributed consortium of researchers who pool intellectual and material resources to accelerate the accumulation of generalizable knowledge in psychology.
