I lead the Multi-source probabilistic inference subgroup of the Complex Systems Computation (CoSCo) group at the Department of Computer Science of University of Helsinki. I am also a member of Helsinki Institute for Information Technology HIIT and The Finnish Center of Excellence in Computational Inference Research (COIN). Until the end of 2012 I was a postdoctoral researcher at the Department of Information and Computer Science, Aalto University, and between March 2015 and June 2015 I was a Visiting Research Scientist at Amazon Berlin. My research interests are in Bayesian modeling of complex data collections. I lead the project "Traces of Information: Intelligence from fragmented data", funded by the Academy of Finland for 2013-2018, which aims at extracting useful intelligence about individuals, groups and communities by combined analysis of seemingly disparate sources of information, such as social media output, spatiotemporal data recorded by various devices, and public data sources.
