Hi! I study personality, and I’m interested in questions such as,

  • How is personality expressed in everyday behavior, like language or social media?
  • How can we measure personality without questionnaires?
  • How is personality related to well-being?

Currently, I’m a postdoc at the University of Pennsylvania, working in the Positive Psychology Center.

I also like learning about new ways to analyze and visualize data. On my blog, I write about working with data, R, predictive modeling, and some research-related stuff.

Some background info is below. For more details, please see my CV.
