PhD Research Fellow in Experimental Particle Physics

Deadline: 28.02.2023

Universitetet i Oslo

The University of Oslo is Norway’s oldest and highest rated institution of research and education with 28 000 students and 7000 employees. Its broad range of academic disciplines and internationally esteemed research communities make UiO an important contributor to society.

The research at the Department of Physics covers a broad range of subfields within physics and technology: From space research to medical physics. A good proportion of the research is interdisciplinary, and conducted in close cooperation with collaborators in Norway and abroad.

Education and teaching are other essential activities. We offer a broad range of courses, and the Department is involved in several study programmes at bachelor’s and master’s level. Some of the best lecturers in Norway are amongst our employees, and we are proud of our prizewinning teaching and learning environment. The Department has 200 employees, of which 50 are permanent scientific positions. On a yearly basis 20 students complete their Ph.D. and 50 finish their M.Sc. degree.

Job description

2-3 positions (depending on funding) as PhD Research Fellow in experimental particle physics is available at the Department of Physics.

No one can be appointed for more than one PhD Research Fellowship period at the University of Oslo. Starting date no later than October 1, 2023.

The fellowship period is 3 years. A fourth year may be considered with a workload of 25 % that normally consists of teaching. This is dependent upon the qualification of the applicant and the current needs of the department.

More about the position

The Norwegian centre for CERN research is looking for 2-3 motivated and talented PhD students for research with the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. The ATLAS experiment is designed to search for new physics in proton-proton collisions and was key to the discovery of the Higgs boson in 2012. The High Energy Physics group (HEP) in Oslo is particularly interested in searches for Dark Matter, Supersymmetry, the Higgs boson and Exotic particles. After the LHC upgrade to High-Luminosity LHC scheduled for 2029, the ATLAS detector will also be upgraded with new and more performant detector systems. The HEP group in Oslo is responsible for building a fraction of the 3D silicon pixel modules for the inner layers of the Inner Tracker (ITK) of ATLAS. In addition, the group contributes to R&D work for future detector technologies relevant for future ATLAS upgrades. The group in Oslo works closely with University of Bergen and SINTEF in addition to CERN.

Position 1. The successful candidate(s) will work on 3D pixel sensors and modules for the ITK upgrade for HL-LHC as well as participate in R&D towards novel sensors together with CERN (e.g. new 3D designs, CMOS technology (e.g. MALTA), quantum sensing). The candidates are expected to strengthen the group’s work on sensor development, detector R&D and instrumentation. TDAQ simulations and/or participation in irradiation and testbeam campaigns as well as analysis of the data from such campaigns will be necessary. Longer stays (ca. 3-18 months) at CERN are required. The successful candidates will have the opportunity to work together with internationally renowned experts and participate in the latest research of future detectors which may contribute to discover new knowledge and get a better understanding of the universe.

Position 2. The successful candidate will contribute to the search for Higgs boson pair production, with an emphasis on the two-photon plus multi-lepton decay channels. This work entails the leveraging of machine learning techniques in order to maximize sensitivity to the low cross section of the signal. The project also provides a natural opportunity to explore and further develop statistical analysis techniques/tools, which will be encouraged.

The candidate(s) will take responsibilities within software and data quality or upgrade- related activities, as part of the necessary ATLAS service work leading to qualification to be author of ATLAS publications. They will participate in shift work to monitor ATLAS data taking. Frequent or long-term stays at CERN are possible and encouraged.

Qualification requirements

The Faculty of Mathematics and Natural Sciences has a strategic ambition to be among Europe’s leading communities for research, education and innovation. Candidates for these fellowships will be selected in accordance with this, and expected to be in the upper segment of their class with respect to academic credentials.


  • Master’s degree or equivalent in particle physics
  • Foreign completed degree (M.Sc.-level) corresponding to a minimum of four years in the Norwegian educational system


  • Position 1: Prior experience in sensor development, detector R&D and instrumentation
  • Position 2: Prior experience in data analysis, the use of statistical methods and tools, as well as machine learning

Candidates without a Master’s degree have until 30 June, 2023 to complete the final exam.

Grade and language requirements:

The norm is as follows:

  • The average grade point for courses included in the Bachelor’s degree must be C or better in the Norwegian educational system.
  • The average grade point for courses included in the Master’s degree must be B or better in the Norwegian educational system.
  • The Master’s thesis must have the grade B or better in the Norwegian educational system
  • Fluent oral and written communication skills in English
  • For candidates who would like to apply for a fourth year including teaching, good knowledge of Norwegian or another Scandinavian language is strongly preferred.
  • English requirements for applicants from outside of EU/ EEA countries and exemptions from the requirements

Personal skills:

  • Good collaboration skills, and the ability to work independently and in an interdisciplinary research environment.
  • Good presentation skills

The purpose of the fellowship is research training leading to the successful completion of a PhD degree.

The fellowship requires admission to the PhD programme at the Faculty of Mathematics and Natural Sciences. The application to the PhD programme must be submitted to the department no later than two months after taking up the position. For more information see:

The position's subject area may require licensing under the Norwegian Export Control Act. In order to be considered for the position, it is a prerequisite that UiO must be able to be granted such licence.

We offer
