UTCS alum Arvind Narayanan, who completed his Ph.D. in 2009, will be starting in the fall at Princeton as a tenure-track assistant professor.

Arvind was advised by Associate Professor Vitaly Shmatikov on his doctoral research, which exposed the problems with data anonymization. He worked with Vitaly on research that gave them the ability to re-identify anonymized data produced by social networking sites Twitter and Flickr that they sell to advertisers. They developed an algorithm that looked at the overlapping information among users of the different sites and analyzed the structure of the individuals’ “network neighborhood.”
