Postdoctoral researcher position in Mathematical Inverse Problems at the University of Helsinki

Updated: about 2 months ago
Deadline: 28 Feb 2024

As part of the Faculty of Science, the Department of Mathematics and Statistics of the University of Helsinki is the biggest university department of mathematical sciences in Finland. The department hosts several current ERC grants of the European Research Council and two Centres of Excellence of the Academy of Finland. We invite applications for

ERC Funded postdoctoral researcher position in Mathematical Inverse Problems at the University of Helsinki

The position will be funded by the ERC advanced grant InversePDE - Geometric Methods in Inverse Problems for Partial Differential Equations and Centre of Excellence on Inverse Modelling and Imaging, led by Professor Matti Lassas.

Position description

The InversePDE project studies inverse problems for partial differential equations (PDEs) and geometric inverse problems. A typical inverse problem is the determination of the coefficient functions of a PDE from indirect data. The project aims to obtain unique solvability and stability results for inverse problems and to develop solution algorithms for these problems that are based on machine learning.

The project will study inverse problems for linear and non-linear hyperbolic and elliptic PDEs by applying analysis, differential geometry, microlocal analysis, and probabilistic methods. The project will also combine methods of machine learning, in particular neural networks, and manifold learning techniques, with the mathematical theory of inverse problems to invent new algorithms that are rigorously guaranteed to work.


We are looking for postdoctoral researchers interested in working on inverse problems and their applications. We also welcome applications from post-docs who have not earlier worked on the above topics but are interested in extending their expertise to new fields. Women and other underrepresented groups in the field of mathematics are strongly encouraged to apply. The University of Helsinki seeks to promote an equitable and inclusive working environment and welcomes applicants of any gender, linguistic and cultural background, or minority group.


The position is for 2 years, with a possible extension to a 3rd year depending on performance and funding.

The starting date may be in the period August 1, 2024- September 1, 2024.

Application deadline is on February 28th, 2024.

Salary and benefits

The starting salary of a Postdoctoral Researcher is typically 3500 - 3800 euros/month, depending on previous qualifications and experience.  

The University of Helsinki offers comprehensive services to its employees, including occupational health care and health insurance, sports facilities, and opportunities for professional development. The University provides support for internationally recruited employees with their transition to work and life in Finland. For more on the University of Helsinki as an employer, please see .
