The UCPH Department of Computer Science () is a department in the Faculty of Science at the University of Copenhagen (UCPH). It is the longest established department of Computer Science in Denmark and was founded in 1970 by Turing Award winner Peter Naur. As of 2021, it employs 82 academic staff, 126 research staff and 38 support staff. It is consistently ranked the top Computer Science department in the Nordic countries, and in 2017 was placed 9th worldwide by the Academic Ranking of World Universities. History DIKU has its roots at the Institute for Mathematical Sciences, where in 1963, the first computer was bought. In 1969, Peter Naur became the first professor in Computer Science at the University of Copenhagen, and in 1970, DIKU was officially established its own department. Research As of 2021, the department is home to 82 academic staff, 126 research staff and 38 support staff. Research is organised into seven research sections: The Algorithms and Complexity Section, headed by Mikkel Thorup, who conduct basic algorithms research, as well as research on data structures and computational complexity The Human‐Centered Computing Section, headed by Kasper Hornbæk, who research human-computer interaction, computer-supported cooperative work, as well as health informatics The Image Section, headed by Kim Steenstrup Pedersen, who work on image processing including medical image processing, computer vision, physics based animation and robotics. The Machine Learning Section, headed by Christina Lioma, researching theoretical machine learning, information retrieval, and machine learning in biology The Natural Language Processing Section, headed by Isabelle Augenstein, who conduct research on core natural language processing, natural language understanding, computational linguistics, as well as multimodal learning The Programming Languages and Theory of Computation section, headed by Martin Elsman, researching programming languages, theory of computation, computer security, and approaches to financial transparency The Software, Data, People & Society Section, headed by Thomas Troels Hildebrandt, who work on decentralised systems, data management systems, and process modelling Teaching The department offers programmes at BSc as well as MSc level, both in core computer science and in interdisciplinary subjects. Bachelor's programmes are 3-year programmes and mostly taught in Danish, whereas Master's programmes are 2-year programmes and taught in English. In 2020, DIKU enrolled 610 new Bachelor's students and 136 new Master's students. As of 2021, DIKU offers the following study programmes: Bachelor of Science (BSc) in Computer Science Bachelor of Science (BSc) in Machine Learning and Data Science Bachelor of
