Paul Butler


I'm a quant in New York City. I love running, sailing, and exploring new cities.

I'm interested in building tools to explore, explain, and persuade. I've developed interactive essays for the Mandelbrot Fractal, the Kelly Criterion, and the mathematical nuance of the US Electoral College. I've written code notebooks for forensic video analysis, L-system fractals, pen-plot route optimization, and surface projection. I create interactive reports on ranked-ballot election results at I created Treeverse, a browser extension for exploring the structure of online conversations as a tree. I think computers are bicycles for the mind and we're still in the penny-farthing era.
