Two to three positions as PhD Research Fellow (3 years) are available at the Rosseland Centre for Solar Physics (RoCS), Institute of Theoretical Astrophysics (ITA), University of Oslo. Starting date is no later than Oct 1, 2026.

One PhD position is connected to the project “Origin and Evolution of Solar Eruptions (OESE)” funded by the Research Council of Norway. The OESE project will study solar eruptions by combining high-resolution observations from the SST on La Palma and observations from telescopes in space such as Solar Orbiter, IRIS, and the upcoming MUSE mission. The supervisors will be prof. Luc Rouppe van der Voort and Dr. Reetika Joshi.

One PhD position focuses on advancing our hybrid PIC and MHD code to enable fully adaptable and self-consistent simulations of the solar atmosphere and solar flares. Both detailed particle physics and fluid dynamics as well as intricacies of coding will be part of this challenging project. The results will be first of its kind. Supervisor will be prof. Boris Gudiksen.

One PhD position is focussing on understanding the formation of dynamic spectra. This project will combine radiative MHD simulations, state-of-the-art spectral synthesis, and multi-instrument observations to get crucial insight on how to interpret the rich solar observations we obtain today. It can focus on different topics, from diagnostics with the upcoming SOLAR-C EUVST telescope, novel methods for radiative transfer, and data science techniques to interpret very large spectral datasets. The supervisor will be prof. Tiago M. D. Pereira.

Application deadline is March 1, 2026
