This site is a fork of the Minimal Mistakes theme for the Jekyll framework. Pages are written in Markdown using Ulysses for Mac, iPhone, and iPad. The site is hosted on GitHub Pages, and I use Tower for Mac and Working Copy for iOS as a git GUI. The entire site is stored in Dropbox for easy editing anywhere, on any device.
The main body font is Activ Grotesk, and the figure captions are Proxima Nova. Both fonts can be found as part of Adobe’s TypeKit.
