Areas of study: 

  • Algorithms and data structures – particular focus on I/O-efficient algorithms and algorithm engineering for massive data sets.
  • Bioinformatics – development and application of models and methods for analyzing biological and biomedical data, covering topics such as algorithmic development, algorithm engineering, software development, and statistical modeling focusing on evolutionary genome analysis, structural bioinformatics and medical bioinformatics.
  • Computer mediated activity – development of new interaction techniques, methods and theories for computer-mediated activities of work and everyday life.
  • Cryptography and security – in particular, public-key cryptography, cryptographic protocols, and quantum cryptography.
  • Data-intensive systems – topics related to spatio-temporal data management, query processing and indexing, high-dimensional and multimedia data, and infrastructure for mobile services and cloud computing.
  • Logic and Semantics - semantics of programming languages and type theories, models and logics for reasoning about programs.
  • Mathematical computer science – computational complexity theory, algorithmic and computational game theory, mathematical programming, combinatorial optimization, computational algebra, real algebraic geometry, and multi-agent systems.
  • Programming languages – object-oriented and functional programming, web technologies, and specification, verification, testing and analysis of software.
  • Ubiquitous computing and interaction – creating concepts for future interactive spaces at schools, libraries, museums, homes, and workplaces.
  • Use, design and innovation – including participatory design in innovation processes.
Employment after graduation:
  • After graduation a majority of our students are employed in the IT industry in the Aarhus area, which includes companies such as Google, Uber, Systematic, and Trifork, however many choose to seek opportunities internationally, and some obtain academic positions either in Denmark or abroad.

The scholarships awarded by the Graduate School of Science and Technology vary depending on the student’s educational qualifications:
  • PhD scholarships are awarded to students who have not yet obtained a master’s degree, that is, students enrolled for an honours master’s degree who have not yet passed the PhD qualifying exam. For students not holding a Danish SU grant (or the equivalent thereof) for their MSc studies, the scholarship amounts to approximately DKK 11.800 per month before tax (2016). For students holding a Danish SU grant (or the equivalent thereof) for their MSc studies, the scholarship amounts to approximately DKK 5.900 per month during the first year of the honours MSc programme, and DKK 11.800 per month for the remaining two years – both before tax (2016).
  • PhD fellowships are awarded when students are admitted on the basis of a master’s degree or have passed the PhD qualifying exam. The fellowship is granted for a period of up to three years, and is granted in accordance with the collective agreement between the Danish Ministry of Finance and the Danish Confederation of Professional Associations, and the amendment of 4 April 2003 regarding PhD scholars. The basic salary amounts to approx. DKK 25,500 per month before tax, excluding pension and holiday. Please note that this only applies when you are employed as a PhD student.
