Postdoc Positions in Computational Complexity

The Theoretical Computer Science Group at KTH Royal Institute of Technology invites applications for postdoctoral positions in computational complexity.

Job Description

The Theoretical Computer Science Group at KTH (www.csc.kth.se/tcs) offers a strong research environment spanning a wide range of research topics such as complexity theory and approximation algorithms, computer and network security, cryptography, formal methods and natural language processing. We have a consistent track record of publishing regularly in the leading theoretical computer science conferences and journals worldwide, and the research conducted here has attracted numerous international awards and grants in recent years.

The postdoctoral researchers will be working in the research group of Jakob Nordström (www.csc.kth.se/~jakobn). Much of the activities of this research group revolve around the themes of proof complexity and SAT solving. On the theoretical side, proof complexity has turned out to have deep, and sometimes surprising, connections to other topics such as, e.g., circuit complexity, communication complexity, and hardness of approximation, and therefore researchers in these or other related areas are more than welcome to apply.

Within the overall framework sketched above, the postdocs will be expected and encouraged to contribute to and influence the research agenda. Taking part in teaching graduate seminar courses is encouraged but not required. Travel funding is included, and the group also receives short-term and long-term visitors on a regular basis.

The research project is financed by a Breakthrough Research Grant from the Swedish Research Council and a Starting Independent Researcher Grant from the European Research Council. A more detailed description of the project can be found at www.csc.kth.se/~jakobn/project-proofcplx. The group currently consists of one postdoctoral researcher and four PhD students (in addition to the research group leader).

These postdoc positions are full-time employed positions for one year with a possible one-year extension. The expected starting date is in August-September 2016, although this is to some extent negotiable.


Applicants should have or be about to receive a PhD degree in a subject relevant for the research area, and should have a passionate interest in research. Exceptional candidates are always of interest regardless of formal prerequisites. Problem solving skills and creativity are a must.

The successful candidate is expected to have a solid background in theoretical computer science (in particular, computational complexity) and mathematics (e.g., in areas such as combinatorics, algebra and/or geometry), and should have a strong research record as witnessed by publications in conferences such as STOC, FOCS, CCC, ICALP, SODA, ITCS, or similar, or in journals of a comparable quality.

The working language of the TCS group is English, and knowledge of English is also fully sufficient to navigate life in Sweden in general. It might also be worth mentioning that Sweden routinely scores at the absolute top in rankings of quality of life such as, e.g., the OECD Better Life Index.


KTH Royal Institute of Technology is the largest and oldest technical university in Sweden. No less than one-third of Sweden's technical research and engineering education capacity at university level is provided by KTH. Education and research spans from natural sciences to all branches of engineering and includes architecture, industrial management and urban planning. There are a total of 12,400 first and second level students and almost 1,900 doctoral students at KTH, and the university has 5,100 employees.

The School of Computer Science and Communication at KTH (KTH CSC) is one of Sweden's leading research and education institutions in information technology, with activities at both KTH and Stockholm University. We conduct education and research in both theoretical and applied computer science. Our activities in theoretical computer science range from theory building and analysis of mathematical models to algorithm construction, implementation and simulation. Applied computer science covers a wide spectrum including computer vision, robotics, machine learning, high performance computing, visualization, computational biology, neuroinformatics and neural networks, and speech and music communication. We also conduct applied research and training in media technology, human-computer interaction, interaction design and sustainable development.
