David Gillis

David Gillis is an Interaction Designer at Teehan+Lax, a Toronto-based company that helps clients define and design great user experiences in the digital channel. There, he's done award-winning information architecture and design work for clients like AOL, AIR MILES, John Hancock and Virgin Mobile. David's passion for interaction design has been informed by a wide range of interests and experiences, both academic and professional. In school, he took a multi-disciplinary approach, combining studies in communication, cognitive science and systems design. He holds Bachelor Degrees in Math and English, and a Masters Degree in Information Systems and Knowledge Media Design. Areas of ongoing interest and investigation for David are evidence-based design (how can designers strike a better balance between intuition and formal inquiry), participatory design (how can designers better engage their clients and end-users in collaborative processes), and holistic design (how can we better design experiences that span across multiple modes, touch points and platforms). David is a regular contributor on the Teehan+Lax blog and you can follow him on Twitter @davegillis.
