I started in psychology because I wanted to know why people do what they do. Four years in, I realised the answers I wanted were sitting inside datasets nobody had bothered to build properly. So I went and learned that too: a postgraduate diploma at UT Austin, then the DACSS master's at UMass Amherst. I am not the person who stops when something works. I am the person who asks what it would take to make it right, and then goes and does that part as well.
