Postdoc Position in Theoretical Computer Science

The Theoretical Computer Science group at KTH Computer Science and Communication (KTH CSC) invites applications for a postdoctoral position in Theoretical Computer Science with a focus on proof complexity and connections to SAT solving.

The Workplace

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 just over 15,000 first and second level students and more than 1,600 doctoral students. KTH has almost 4,300 employees.

The School of Computer Science and Communication (KTH CSC) is one of Sweden's leading research and education institutions in Information Technology, with activities at both KTH and Stockholm University. The activities of the school focus on higher education and research within the traditional core areas of numerical analysis and computer science; from theory building and analysis of mathematical models to algorithm construction, implementation and simulation. Other core areas of growing importance are technology and methods for the support of human communication and computer mediated cooperation. The applied research includes scientific computing, computer science, computer vision, robotics, neuroinformatics and neural networks, human-computer interaction, media technology, and communication through speech and music. For more information, see www.kth.se/en/csc.

The Theoretical Computer Science group at KTH CSC (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. The group has 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.

Assignment

We are seeking a postdoctoral researcher in Theoretical Computer Science within the framework of the research project "Understanding the Hardness of Theorem Proving." This is a project in proof complexity with connections to SAT solving.

Proof complexity studies formal systems for reasoning about logic formulas. This field has deep connections to fundamental questions in computational complexity, but another important motivation is the connection to SAT solving. All SAT solvers use some kind of method or system in which proofs are searched for, and proof complexity analyses the potential and limitations of such proof systems (and thereby of the algorithms using them).

This project aims to advance the frontiers of proof complexity, and to leverage this research to shed light on questions related to SAT solving. We are particularly interested in exploring the possibility of basing SAT solvers on stronger proof systems than are currently being used. In order to do so, however, a crucial step is to obtain a better understanding of the corresponding proof systems, and in this context there are a number of well-known and relatively longstanding open questions in proof complexity that we want to study and try to solve. A more detailed description of the project can be found at www.csc.kth.se/~jakobn/project-proofcplx.

The project is led by Jakob Nordström (www.csc.kth.se/~jakobn) and is financed by a Breakthrough Research Grant from the Swedish Research Council and a Starting Independent Researcher Grant from the European Research Council. The group currently consists of one postdoctoral researcher and two PhD students (in addition to the project leader). Within the overall framework sketched above, the postdoc will be expected and encouraged to contribute to and influence the development of the project. Taking part in teaching a graduate seminar course (in proof complexity or neighbouring areas) is encouraged but not required. Travel funding is included, and the group also receives short-term and long-term visitors on a regular basis.

This is a full-time employed position for one year with a possible one-year extension. The successful candidate is expected to start at the latest in August-September 2013, although this is to some extent negotiable.

Employment

Form of employment: One year temporary position with a possible one-year extension
Work time: Full time
Start date: By agreement, but preferably no later than August-September 2013
Number of positions: 1

Qualifications

Applicants should have or be about to receive a PhD degree in a subject relevant for the research area, such as Computer Science or Mathematics (preferably focused on proof complexity or neighbouring areas), and should have a passionate interest in research.

The successful candidate is expected to have a solid background in Theoretical Computer Science (computational complexity) and Mathematics (in areas such as combinatorics, algebra and/or geometry). Exceptional candidates are always of interest regardless of formal prerequisites. Problem solving skills and creativity are a must.

The working language of the TCS group is English, and knowledge of English is also fully sufficient to navigate life in Sweden in general.

Application

Application deadline: January 14, 2013
Employer's reference: D-2012-0444

Applications should be sent via email to jobs@csc.kth.se. Write the reference number in the subject line. The application and all attachments should be sent as PDF files.
