I study personality expression in the digital space, using computational methods like machine learning and natural language processing. I have shown that personalities inferred from people’s Facebook profiles are more accurate than judgements made by friends, roommates, family members, and romantic partners. 

As a psychologist of this generation, I am also drawn to metascience and methodology, and particularly reproducibility.I am interested in how we can best predict replication outcomes before anactual replication takes place. I am currently ranking the replicability of>10k Psychology publications in top-tier journals using machine learning,for scientists to prioritize manual replications of certain studies.
