Henry Tirri

Research Fellow
Head of NRC System Research
Nokia Research Center

I am currently responsible for the research at the NRC Systems Research laboratories worldwide striving for disruptive systems research with open innovation collaboration globally. NRC SR laboratories thrive to enable new business opportunities for Nokia by extending the traditional Nokia realm of research, with strong relations to and a strong presence in world leading innovation ecosystems such as Silicon Valley, Beijing, Cambridge(MA), Bangalore and Cambridge (UK). I am also a Professor of Computer Science (University of Helsinki), and an Adjunct Professor of Computational Engineering (Helsinki University of Technology).

Recent cool advances from NRC Systems Research Laboratories

Research interests (i.e., what makes me tick)

My general research interests are related to intelligence in machines. As reasoning under uncertainty is one central aspect of intelligent behavior, the last 20 years I have been interested in fundamental questions related to building models from data, and performing (predictive) inference from such models (related to "data analysis"). In this broad area my main focus is on probabilistic and information-theoretic approaches, both the theoretical properties and multidisciplinary applications. Some of the results of the research (with CoSCo research group) have been implemented in B-Course data analysis service. For some time I have been particularly interested in applying these modeling methods in information retrieval including Internet search engines and wireless sensor networks. In general I am interested in adaptive systems, and related notions of the above topics, such as context-awareness, community-based computing and data analysis for future networks in general. Some of my recent research activities are reflected in Sensorplanet. I am particularly excited in developing applications and services that do not "scale-down" but allow millions of computing devices to interact and implement very large-scale applications.
