While not making fast, accessible, responsive websites at Bocoup, Mat “Wilto” Marquis is a carpenter, boxer, aspiring French chef, British motorcycle mechanic, and mediocre Mega Man 2 speed-runner.

As Chair of the Responsive Issues Community Group, Mat spearheaded the effort to bring native responsive image solutions to the HTML5 specification, later going on to facilitate browser implementations and oversee the addition of native responsive image techniques to major CMSes. A former editor at A List Apart and member of the jQuery team, Mat is now a frequent An Event Apart speaker, and recently had the honor of appearing in the film What Comes Next is the Future.

He recently published his first book, JavaScript for Web Designers, with A Book Apart.

He keeps busy.
