Doctoral Researcher, Solar and Space Physics
Doctoral Researcher in Solar & Space Physics
The Space Physics Group at the University of Helsinki invites applications for a fully funded 4 year PhD position in solar and heliophysics. The position is part of the newly funded Research Council of Finland project Redefining Inner Boundaries in Solar Wind Models (RIB-Wind), led by Dr. Stephan G. Heinemann. The preferred start date is October 2025, but later dates are negotiable.
Project Background: Modeling the origin and acceleration of the solar wind remains a central challenge in heliophysics, with major implications for both fundamental plasma physics and space weather forecasting. The RIB-Wind project aims to overcome key limitations in current heliospheric models, which typically rely on empirical assumptions to define inner boundary conditions (around 0.1 au from the Sun). By combining high-resolution remote sensing data (especially EUV spectral imaging) with advanced simulations, RIB-Wind seeks to more accurately characterize the solar wind near its source—redefining how inner boundaries are set and significantly improving global solar wind models and forecast capabilities.
Role of the Doctoral Researcher: The selected candidate will contribute to several aspects of the project, including the analysis of EUV observations (both on-disk and off-limb) and in-situ measurements, modeling of coronal magnetic fields to map magnetic connectivity, and running and interpreting one- to three-dimensional solar wind simulations to define new inner boundary conditions for global heliospheric models.
Requirements:
- MSc (or equivalent) in space physics, astrophysics, or a related discipline completed by the time of appointment,
- Strong interest in solar physics, space weather, or plasma modeling,
- Programming experience (e.g., Python or equivalent),
- Some background in solar data analysis or simulations is helpful, but not mandatory.
- Proficiency in written and spoken English.
The employment contract will include a probationary period of six months.
The appointee should either already have the right to pursue a doctoral degree at the University of Helsinki by the start of the appointment or apply for the right and obtain it within the probationary period of six months of their appointment. If the candidate does not already have the right to pursue a doctoral degree at the University of Helsinki, it must be applied for separately (www.helsinki.fi/en/research/doctoral-education/the-application-process-in-a-nutshell). The requirements for pursuing a doctoral degree at the University of Helsinki can be found at https://www.helsinki.fi/en/research/doctoral-education/eligibility-and-educational-documents.
