Currently I work for Google, and am an engineer on the Android platform team, working on fonts and text layout. Before then, I worked on the Web Fonts team, and before that, on spam in apps.
For fun, I tinker with emulating vintage synthesizers. You can find source code and Play Store links on my Android projects page.
I used to be maintainer of Ghostscript, and have played a role in a number of other free software projects.
I have a number of patents, all of which are available for licensing, and all of which are subject to a patent grant for GPL-licensed software. A special prize is the Even Toned Screening, an exceptionally high quality suite of halftoning algorithms for inkjet printers.
I have completed a PhD on techniques for interactive curve design. Spiro is a free software library containing these techniques, and I also used them to design a number of fonts, including Inconsolata.
You may also be interested in a draft of an earlier attempt at a PhD, on Attack-Resistant Trust Metrics. The best source for that work is the chapter in Computing with Social Trust.
I have a Wikipedia entry.
I'm a member of the Berkeley Monthly Meeting of the Religious Society of Friends (Quakers).
I live in Berkeley, California. I'm father of two amazing boys, Alan and Max.
