With a focus on designing for knowledge work, Colin teaches the effective use of knowledge and information systems to improve organizational performance. Prior to his university appointment, Colin was an infection control epidemiologist, developing an innovative technology to measure hand hygiene behaviours beyond the W.H.O. moments for hand hygiene. Using this new tool, he collaborated on research which quantified the Hawthorne Effect in hand hygiene behaviour, and which achieved the first objective measurement of patient hand hygiene behaviour.
