John Hopcroft was a recipient of a Microsoft Research Outstanding Collaborator Award. He was cited for his membership on the Microsoft Research Asia (MSRA) Technical Advisory Board; for being one of the strongest advocates for MSR among talented students in China (MSRA has hired over half of his top computer science undergraduates as interns); strengthening the collaboration between MSR and key academic partners; and, in collaboration with MSR researchers Christian Borgs and Jennifer Chayes for over a decade, developing influential network algorithms for decreasing web spam and for identifying communities in massive networks.

Also receiving the award was Stephanie Weirich, who received her PhD from Cornell CS in 2002 and is now full professor at the University of Pennsylvania.
