Youyou Wu 

pronounced as yo-yo


I am a Lecturer (Assistant Professor) in Psychology at University College London (UCL), Faculty of Education and Society (IOE), Department of Psychology and Human Development. I obtained my PhD in Psychology from the University of Cambridge. I was also a postdoctoral researcher at Northwestern Institute of Complex Systems (NICO) at Kellogg School of Management, Northwestern University. 

I study personality expression in the digital space, using computational methods like machine learning and natural language processing. My most prominent work shows that personalities inferred from people’s Facebook profiles are more accurate than judgements made by friends, roommates, family members, and romantic partners. This line of research has stimulated continuous discussions and applications in industries that involve personality assessment, including insurance, marketing, politics, and gaming.

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 an actual replication takes place. 

My work has appeared in journals like PNAS, Nature Communications, and Psychological Science. It has been covered by global outlets like BBC, New York Times, and the Economist. It has also been cited in policy documents by the European Union, the Australian government, and think tanks including the Brookings Institution and the Rathenau Institute
