I'm Stephen Green, the Principal Investigator of Advanced Search Technologies for Sun Labsin Burlington, Massachusetts.
I joined Sun Labs in 1999 after a two year postdoc at Macquarie University in Sydney, Australia. I got my Bachelor's and Master's degrees from the University of Waterloo in 1990 and 1992, respectively. I received my Ph.D. in Computer Science from the Univerity of Toronto, in 1997 (that's Dr. Search Guy to you!)
In case the Universities aren't a dead giveaway, I'm Canadian.
