Marie Curie PhD position in Physics Applications of Negative Ions (PANIONS)

What you'll do

You will join the EU-funded Horizon Europe Doctoral Network Physics and Applications of Negative Ions (PANIONS), an ambitious research programme exploring the properties and applications of negative ions across a wide range of fields. Negative ions occur in many natural environments and are used in modern applications. Their unique properties make them ideal quantum systems for benchmarking state-of-the-art theories in atomic and molecular physics.

As a Doctoral Candidate, you will contribute to advancing the understanding of negative ions from atomic to cosmic scales, helping bridge the gap between fundamental science and applications. The PANIONS network brings together 14 Doctoral Candidates across 11 host institutions in Europe, combining advanced theoretical models and sophisticated experimental methods to study atomic and molecular anions and their interactions in environments ranging from vacuum and plasmas to interstellar clouds and planetary surfaces.

Within this programme, you will develop a broad scientific and technical skillset and collaborate with leading European research infrastructures while completing an internship with a relevant industrial company. The position (DC12) is offered within the framework of the Marie Skłodowska-Curie Actions, which train young researchers and support the careers of tomorrow’s leaders in research and industry.
