Belén is a senior interaction designer with LBi UK, and she is nuts about 1) Mobile and 2) Prototyping in that order. Before landing in London, she was the “mobile person” in iQ Content. She advised clients about mobile strategy and mobile web design, gave training on mobile user experience, and drove iQ Content’s forays into the mobile space. She writes about mobile at http://belenpena.posterous.com, and tries hard not to take anything too seriously.
