What you'll do

You will join one of CERN’s experimental physics groups, if selected for this Research Fellowship, to develop and lead your own research programme at the frontier of particle physics. You will work in a highly collaborative and international environment, analysing data, contributing to detector design, construction and/or operations, and engaging in the design, execution and interpretation of physics data analyses. You will also be part of CERN’s vibrant scientific community through seminars, workshops, training activities and collaborative projects.

Your key tasks

• You conduct research in experimental physics within a CERN research group of your choice.
• You contribute to CERN’s experimental physics programme using its large-scale scientific instruments.
• You collaborate with physicists and engineers on studies of particle interactions and related research activities.
• You develop and pursue your research interests within the framework of the Fellowship.

Your profile

• You hold a strong background in experimental particle physics or a closely related field.
• You have research experience aligned with the scientific activities carried out at CERN’s experimental facilities.
• You are motivated to join a research group and contribute to high-impact scientific work.
• You are eager to develop and pursue your own research interests within the Fellowship framework.

Your skills

• You have solid analytical and problem-solving skills in the context of experimental physics.
• You are able to work collaboratively within large, international scientific teams.
• You communicate effectively in a scientific environment, including presenting and discussing research results.
• You can work independently while contributing to shared research objectives and collaborative projects.
