The focus of the department's research activity is on advanced computational methods for modelling, analysing, and solving complex tasks in technology and science. The research aims at the development of fundamental computer science methods for the analysis of large and high-dimensional data sets, and for the modelling and design of complex software, networking and other computational systems.
The department hosts three national Centres of Excellence: the Centre of Excellence in Computational Inference Research and parts of the Centres of Excellence in Molecular Systems Immunology and Physiology Research and Research on Solar Long-Term Variability and Effects. The department also contributes to the Helsinki Institute for Information Technology HIIT and the Helsinki node of the EIT ICT Labs. The department is a member of Informatics Europe, the association of European computer science departments.
The research groups at the Department of Information and Computer Science are:
