My research focuses on data mining and algorithmic data analysis. I am particular interested in algorithms for graphs, social-network analysis, and algorithms for web-scale data.
Before coming to Aalto I was a senior research scientist in Yahoo! Research, and previously an Academy of Finland postdoctoral scientist in the University of Helsinki. I obtained my Ph.D. from Stanford University in 2003. During my doctorate studies I had the pleasure to work as a summer intern in Microsoft Research, AT&T Labs, and Bell Labs Lucent Technologies.
