Lewis Lehe

I'm a lecturer in civil engineering at UC Berkeley, where I teach the graduate course in public transit operations. In December 2016 I received my PhD in Civil Engineering at Berkeley, where my advisor was Carlos Daganzo. I study traffic theory and urban economics. My goal is to make models helpful to the design of pricing and regulation. I code for my papers in Julia and Python. 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.
