I am a data scientist in psychology. I use Facebook and Twitter to measure the psychological states of large populations. We are finding out what makes communities sick and what drives their well-being. Through Facebook and billions of tweets, not landlines.

Formally, I’m a PhD student in psychology at the University of Pennsylvania under Martin Seligman. In 2011 I co-founded the World Well-Being Project, a team that uses clever Natural Language Processing and machine learning to, well, measure the well-being of the world. Eventually.

I was born in Mexico, raised in Germany, and now live in Philly. I hold a B.S. in physics & philosophy from the University of London, a M.S. in physics from the University of Chicago, a MA in psychology and Master of Applied Positive Psychology from the University of Pennsylvania. I enjoy hiking.
