Henry Tirri

Executive Vice President, CTO, Dr., Dr.h.c.

I am currently the Chief Technology Officer of Nokia. The mandate of the CTO and the associated organization is to drive the current and future technological competitiveness of Nokia. CTO owns the forward-looking Future Technology part of the Nokia strategy. In addition my Nokia role I am also an Adjunct Professor of Computer Science (University of Helsinki), and an Adjunct Professor of Computational Engineering (Helsinki University of Technology).

Professional Activities

I was an ISTAG Member 2007-2009. I was nominated to join the IEEE Computer Society Industry Advisory Board (IAB) for 2009-2011. Member of the Scientific Advisory Board of Institute for Infocom Research and member of the International Advisory Committee of Tsinghua National Laboratory for Information Science and Technology. I am also on the Boards of SVForum, HIIT and Cicero. Nokia is also the sponsor of the Health Category of the Humanitarian Tech Awards (2009- ) - one of my passions as well as Nokia Sensing X Challenge (2012-2015) which I am the proud sponsor of.

I am currently in the Editorial Boards of IEEE Signal Processing, International Journal of Mobile CommunicationsWeb Intelligence and Agent SystemsInternational Journal of Neural Systems

Research Interests

During my career my general research interests have been related to intelligence in machines. Reasoning under uncertainty is one central aspect of intelligent behavior, consequently 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"). After exploring many paradigms from rule-based deterministic models to semantic nets I have found the probabilistic and information-theoretic approaches to be the most interesting and powerful. Some of the results of the research (with my former CoSCo research group) have been implemented in B-Course data analysis service. Recent years I have been particularly interested in applying these modeling methods to information retrieval including Internet search engines and wireless sensor networks.  What excites me currently is the possibility to develop applications and services that do not "scale-down" but allow millions of computing devices to interact and implement very large-scale services depending on contextual data. I am also fascinated by the role of energy in computing - I anticipate the energy dimension to be even more fundamental than memory and computing  in the future.
