for the position of
POSTDOCTORAL RESEARCHER

We are announcing one position for the job of Assistant with a Doctorate degree (postdoctoral researcher).

The position is available at the Department of Mathematics. The applicant is expected to take a leadership role in one of the following research directions:

• nonclassical action-angle variables for nonlinear integrable equations with rough initial data,
• convergence and stability estimates for NLFT-based numerical algorithms,
• asymptotic behavior of the prediction error for stationary Gaussian processes,
• quantitative universality for orthogonal polynomials and random matrices,
• scattering characterization of relativistic crystals (described by Dirac operators with potentials supported on a countable set).  

Job Description:

• conducting scientific research in accordance with legislation in the field of scientific research and innovation activities,
• publishing scientific articles,
• applying for independent funding with IMFM as a host institution during the first year at IMFM.

Required education and title:

• completed Doctorate degree.

Successful candidate will be appointed to the title of Assistant with a Doctorate degree (in case she/he does not have this title at the moment of application) no later than the day of signing the employment contract.

We expect that the candidate:

• has strong results in spectral or scattering theory of Schrodinger, Dirac, Jacobi, or Krein operators, or has an exceptionally strong results in the broader area of one-dimensional complex analysis, operator theory, nonlinear integral equations, or probability,
• will publish high-impact research papers,
• is fluent in English.

What we offer:

• dynamic research work with opportunities for personal and professional development, in one of the above directions with the project leader Roman Bessonov and other members of analysis and spectral theory group in Ljubljana,
• competitive salary,
• good working conditions,
• generous financial support for participating in scientific events,
• employment for a fixed term of 1 or 2 years, with the anticipated start date of January 1, 2027.

Ensuring equal opportunities:
The Institute of Mathematics, Physics and Mechanics ensures gender equality and prevents any form of discrimination among individuals applying for vacant positions.

Candidates are invited to submit their application as a single PDF file, to the email address roman.bessonov@imfm.si, with the subject "Postdoctoral researcher at IMFM" no later than June 30, 2026. The application should include:

• a cover letter mentioning basic facts on your education, work experience, and the preferred duration of the position at IMFM (1 or 2 years). Please also provide a contact detail of two academic referees able to write support letters upon request; 
• a curriculum vitae with MathSciNet Author ID and the list of publications; 
• proof of education. 

The formal approvement of the candidate and the official offer from IMFM is expected in August 2026. The selected candidates will be invited for an interview via email.
