I am an Associate Professor in Organizational Behavior at Stanford University Graduate School of Business. I study humans in a digital environment using cutting-edge computational methods, AI and Big Data. I have co-authored Modern Psychometrics, a popular textbook, and published over 90 peer-reviewed papers in leading journals including Proceedings of the National Academy of Sciences (PNAS), Nature Scientific Reports, Psychological Science, Journal of Personality and Social Psychology (JPSP), and Machine Learning, that have been cited over 18,000 times. I am among the Top 1% of the Highly Cited Researchers according to Clarivate. My research inspired a cover of The Economist, a 2014 theatre play “Privacy”, multiple TED talks, a video game, and was discussed in thousands of press articles, books, podcasts, and documentaries. In 2015 I received a Rising Star award from the Association of Psychological Science. 

I was behind the first press article warning against Cambridge Analytica. My research exposed the privacy risks that they have exploited and measured the efficiency of their methods. You can learn more about it in Steven Levy's awesome book "Facebook: The Inside Story"

I hold a doctorate in psychology from the University of Cambridge and master's degrees in psychometrics and in social psychology. Before my current appointment, I was a post-doctoral scholar at Stanford's Computer Science Department, the Deputy Director of the University of Cambridge Psychometrics Centre, and a researcher at Microsoft Research (Machine Learning Group)

I donate at least 10% of my income to effective charities. Perhaps I could inspire you to do the same!
