Research Interests
My interests are in all aspects of the "data lifecycle", from data collection and cleaning, through mining and analytics, and private data release. More details in my list of publications.
Biography
From 2004-06, I worked at Bell Laboratories in the Internet Management Research Department. From 2006-2013, I was a researcher at AT&T Labs-Research. Between 2002 and 2004, I was a postdoctoral fellow at DIMACS, the Center for Discrete Mathematics and Computer Science. I completed my PhD at the Department of Computer Science at the University of Warwick, UK in 2002. I spent a year of my PhD studying in Cleveland, Ohio at Case Western Reserve University with the Electrical Engineering and Computer Science Department , and Summer 2000 at AT&T Shannon research labs.
