Daniel M Russell is a research scientist at Google where he works in the area of search quality, with a focus on understanding what makes Google users happy in their use of web search. He studies how people do their searches, trying to understand the most common traps and pathways to successful Google use. Dan has been a researcher at IBM's Almaden Research Center, Apple's Advanced Technology Group and Xerox PARC. He received his PhD from the University of Rochester before there was a world-wide web, and remembers a time when email addresses didn't end in .com or .edu. He enjoys long distance running, making music and word play, becoming disgruntled when he can't do all three in one day.
