PhD Position in Theoretical Computer Science and/or Combinatorial Optimization
The Department of Computer Science at Lund University invites applications for a PhD position in theoretical computer science and/or combinatorial optimization.
The PhD student will be working in the Mathematical Insights into Algorithms for Optimization (MIAO) group headed by Jakob Nordström, which is active at both Lund University and the University of Copenhagen on either side of the Öresund Bridge.
The MIAO research group has a unique profile in that we are doing cutting-edge research both on the mathematical foundations of efficient computation and on state-of-the-art practical algorithms for real-world problems. This creates a very special environment, where we do not only conduct in-depth research on different theoretical and applied topics, but where different lines of research cross-fertilise each other and unexpected and exciting synergies often arise. Much of the activities of the group revolve around powerful algorithmic paradigms such as, e.g., Boolean satisfiability (SAT) solving, Gröbner basis computations, integer linear programming, and constraint programming. This leads to classical questions in computational complexity theory—though often with new, fascinating twists—but also involves work on devising clever algorithms that can exploit the power of such paradigms in practice.
Our most recent new line of research is on how to verify the correctness of state-of-the-art algorithms for combinatorial optimization. Such algorithms are often highly complex, and even mature commercial solvers are known to sometimes produce wrong results. Our work on designing a new generation of certifying combinatorial solvers, which output not only a answer but also a machine-verifiable mathematical proof that this answer is correct, has already received several international awards, but many more exciting problems are still waiting to be solved!
With this call, we are mainly looking for a mathematically gifted PhD student with excellent programming skills to continue our ground-breaking work on certifying algorithms, funded by the Wallenberg AI, Autonomous Systems and Software Program (WASP). There is some flexibility as to what kind of research PhD students in the group pursue, though, and all candidates are welcome, both those who want to go deep into either theory or practice and those who are inspired by the challenge of bridging the gap between the two. Please see the description of the MIAO group to learn more about our work.
Our PhD positions are four-year full-time employed positions, but they usually (though not necessarily) include 20% teaching, in which case they are prolonged for one more year. The starting date is negotiable, but should ideally be during the autumn of 2023 or in early 2024. All positions in the research group are fully funded, employed positions (including travel money) that come with an internationally competitive salary.
To be eligible to apply for this position, applicants need to have or be close to obtaining either an MSc degree or a 4-year BSc degree. A suitable background is, for instance, a degree in computer science, mathematics, electrical engineering, or possibly technical physics with a theoretical specialization.
The successful candidate is expected to have a strong background and passionate interest in computer science and mathematics. Problem solving skills and creativity are a must. For candidates aiming to do more applied research excellent programming skills are also crucial.
The working language of the group is English, and knowledge of English is also fully sufficient to navigate every-day life in Scandinavia in general. It might also be worth mentioning that Scandinavian countries routinely score at the absolute top in rankings of quality of life such as, e.g., the OECD Better Life Index.
Lund University was founded in 1666 and is repeatedly ranked among the top 100 universities in the world. Lund Technical College (LTH) forms the Faculty of Engineering at Lund University, where research of the highest international standard is conducted.
The Department of Computer Science at LTH is a partner in the Wallenberg AI, Autonomous Systems and Software Program (WASP), which is Sweden's largest ever individual research program and addresses research on artificial intelligence broadly construed, and also in the ELLIIT Excellence Centre focused on basic and applied research in information technologies. Furthermore, there are extensive collaborations with the University of Copenhagen, the IT University of Copenhagen (ITU), and the Technical University of Denmark (DTU) on the other side of the Öresund Bridge.
The application deadline is September 25, 2023 at midnight local time.
Applications must be submitted via the Lund University recruitment system. Please see the official advertisement at lu.varbi.com/what:job/jobID:650378/ for more details including a link to the application form.
The application should include the following documents:
Please observe that all the documents above should be in English (or for official documents possibly in Swedish).
Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset.
