Research Fellowship Theoretical Physics

You will join one of CERNs theoretical physics research groups if selected for this Research Fellowship to develop and lead your own research programme at the frontier of fundamental physics. You will work in a highly collaborative and international environment contributing to the development of theoretical models performing analytical and computational research and advancing the understanding of particle physics and related fields.

You will also be part of CERNs vibrant scientific community through seminars workshops training activities and collaborative projects.

Your key tasks

• You conduct research in theoretical physics.
• You contribute to CERNs theoretical physics programme by developing innovative theoretical approaches and advancing the interpretation of experimental results.
• You collaborate with theoretical and experimental physicists on research related to particle physics and fundamental interactions.
• You develop and pursue your own research interests within the framework of the Fellowship.

Your profile

• You hold a PhD in theoretical physics or have a scheduled PhD defence before taking up your appointment at CERN.
• You have no more than six years of research experience after completing your PhD.
• You have a strong background in theoretical particle physics or a closely related field.
• You have research experience aligned with the scientific activities carried out within CERNs Theory Department.
• You are motivated to join a leading international research environment and contribute to high-impact scientific research.
• You are eager to develop and pursue your own research interests within the Fellowship framework.

Your skills

• You have strong analytical and problem-solving skills in the context of theoretical 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.
