Updated: about 2 months ago
Job Type: FullTime
Deadline: 30 Sep 2021

The University of Helsinki ( ), is an international scientific community of 40,000 students and researchers. It is one of the leading multidisciplinary research universities in Europe and ranks among the top 100 international universities in the world.

The Department of Mathematics and Statistics ( ) is the largest university department for mathematical sciences in Finland. The multifaceted research carried out at the Department of Mathematics and Statistics has received the highest points in several evaluations. The department collaborates actively with other universities, as well as with many research institutes in the sector, both at home and abroad. The department belongs to the Faculty of Science. The department is located at the Kumpula Campus.

The Department of Mathematics and Statistics, Faculty of Sciences, University of Helsinki invites applications for a

PhD student or Postdoctoral Researcher in Online Optimization for Dynamic Inversion

Background and aim

Time-dependent inverse problems are experiencing a concerted increase in research effort.

The simplest example is video reconstruction while more advanced problems include industrial and other process monitoring, such as the flow of a fluid in a tube to detect impurities. Efficient computational tools for the solution of dynamic inverse problems are, however, largely non-existent: the problems are dynamic, but the algorithms are not. They need to be run offline after taking measurements for a long time interval. There is therefore an urgent need to develop “online” algorithms that can in real-time process newly arriving data---and to understand what these algorithms solve. We aim to do exactly these two things.

The research will be carried out in close contact with the Finnish Centre of Excellence in Inverse Modelling and Imaging.

Funding and requirements

The salary is based on the salary system of Finnish universities and the project is funded by the Academy of Finland. The starting date is negotiable.

For a post-doctoral researcher, the starting salary will be 3200–3800€/month, depending on the appointee’s qualifications and experience. The contract will be made initially for two years.

For a PhD student the starting salary will be ca. 2400€/month and funding is available until August 2025.

For being hired as a postdoc, candidates should have

  • PhD degree in mathematics or a related field such as computer science or physics (with proof of abilities in mathematics) by the start date of the position.
  • Past research experience in optimization methods and/or inverse problems.
  • Ability to work independently.

For being hired as a PhD student, candidates should have

  • By the start date of the position, a Master’s degree in mathematics with excellent grades and thesis evaluation
  • Preferably past experience (e.g. M.Sc thesis) in the area of mathematical optimization methods and/or inverse problems.
  • Either the right to pursue a doctoral degree in the Doctoral Programme in Mathematics and Statistics (Domast) at the University of Helsinki by the start of the appointment, or apply for the right and obtain it within the probationary period of 6 months applied in the appointment. For more information on the Domast: .
