Lewis Lehe

I write code and do research in traffic theory and urban economics. In December 2016 I received my PhD in Civil Engineering at UC Berkeley, where my advisor was Carlos Daganzo. In my free time I read, swing kettlebells and create data visualizations using d3.js and React. I'm from the suburbs of Birmingham, Alabama.
