The Department of Computer Science was established in 2016 when three departments at Aalto University were merged. The three previous departments were the Department of Computer Science and Engineering, the Department of Information and Computer Science and the Department of Media Technology.

The previous Computer Science and Engineering (CSE) department had a long tradition in high-impact, broad-scale and cross-disciplinary applied and basic scientific research for instance in data communications software, software technology, software engineering and software business.

The focus of the research and teaching activity at the former Information and Computer Science (ICS) department was on advanced computational methods for modelling, analysing, and solving complex tasks in technology and science. The research aimed 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.

Research in Computer Science

In all research areas, we embrace theory and applications, enabling high-impact scientific discoveries and socially relevant applications.
