Introduction

The CERN Research Fellowship 2027 in Switzerland is accepting applications from researchers working in theoretical physics. It offers an opportunity to join a research group in CERN’s theory department and collaborate with researchers from different academic backgrounds. Applicants must hold a PhD in theoretical physics or have a PhD defense scheduled before their appointment begins. The application deadline is 2 November 2026.

The fellowship combines research experience with financial support, employment benefits, and training. Its benefits include a monthly net stipend, health insurance, pension fund membership, and paid leave. Travel, relocation, and family-related support depend on the researcher’s individual circumstances. Applicants should review both the eligibility conditions and required documents before preparing their online submission.

Scholarship Overview

This is a research fellowship rather than a scholarship for completing an undergraduate or postgraduate degree. It is described as fully funded and provides an employment contract lasting 24 months, with a possible extension of up to 36 months. Fellows will have the opportunity to conduct research within CERN’s theory department. The program is intended for researchers with a strong background in theoretical particle physics or a closely related field.

Host Country

The fellowship is listed as an opportunity in Switzerland. CERN’s laboratory is situated near Geneva on the border between France and Switzerland. This location provides the setting for the research appointment and collaboration within the organization. Applicants planning a move should distinguish between the fellowship’s stated benefits and support that depends on personal circumstances.

Host Institution or Organization

CERN, formally known as the European Organization for Nuclear Research, was founded in 1954. Its physicists and engineers investigate the fundamental structure of the universe. The organization is one of the world’s largest research centers, and diversity has been part of its mission since its establishment. Fellowship participants will have the opportunity to work in a research group within its theory department.

Degree Level

The fellowship is aimed at researchers at the PhD stage or beyond. Candidates must already have a PhD in theoretical physics or have their defense scheduled before taking up the CERN appointment. An additional eligibility condition limits applicants to no more than six years of research experience after completing their PhD. These conditions should be considered together when assessing whether to apply.

Available Fields of Study

The fellowship focuses on theoretical physics, with a requirement for a strong background in theoretical particle physics or a closely related field. Applicants must submit a statement describing their research interests as part of the application. That statement gives candidates a place to explain their academic focus and research direction. The opportunity involves research within CERN’s theory department rather than enrollment in a taught degree program.

Scholarship Benefits

Successful applicants will receive a monthly net stipend of 7,004 or 7,425 Swiss francs, depending on their degree. CERN also provides health insurance covering the researcher, their spouse, and their children. Fellows receive membership in the CERN Pension Fund and paid leave. Several additional benefits are dependent on the researcher’s circumstances.

• Contract: A 24-month employment contract, with a possible extension of up to 36 months.
• Travel and relocation: Coverage according to individual circumstances.
• Leave: 30 days of paid leave per year, plus two weeks of annual closure.
• Family support: Child, family, and infant allowances depending on circumstances.
• Training: On-the-job and formal training, including language classes.
• Research experience: An opportunity to work at one of the world’s largest research centers.

Eligibility Criteria

Applicants should check every eligibility condition before investing time in their submission. The academic requirements cover both doctoral status and the applicant’s research background. The fellowship also places a limit on post-PhD research experience. CERN staff members are excluded from applying.

• Hold a PhD in theoretical physics, or have a PhD defense scheduled before starting the appointment.
• Have no more than six years of research experience after completing the PhD.
• Demonstrate a strong background in theoretical particle physics or a closely related field.
• Not be a CERN staff member.

Required Documents

The application requires a CV or resume, the researcher’s recent qualification, three recent recommendation letters, and a statement of research interests. The CV must be uploaded in PDF format alongside the other application documents. Applicants must also enter information about their referees during the online process. Preparing these materials early can help avoid last-minute coordination problems.

Application Process

Applications are submitted online through CERN’s official website. Candidates must provide personal and educational information, including details such as their name, address, date of birth, and country. They should upload their detailed CV in PDF format together with the required supporting documents. The application also asks researchers to state their research interests.

Applicants must provide referee information so recommendation letters can be written or uploaded. Before submission, candidates should carefully review the completed form and attached files. All parts of the application should be completed before the deadline. General preparation advice below is intended to support this process, not to introduce additional fellowship requirements.

Important Dates and Deadline

The deadline for the CERN Research Fellowship 2027 is 2 November 2026. Applicants should plan document preparation and referee coordination around that date. As a general precaution, submitting ahead of the final day leaves time to address upload or form-completion difficulties. Candidates should review any timing instructions displayed on CERN’s official application platform.

Tips for Applicants

As general application guidance, begin by making a checklist of the stated eligibility conditions and required materials. Keep your CV, qualification document, research interests statement, and referee details together in an organized folder. Use clear file names so each document is easy to identify during upload. Check that the PDF version of your CV opens correctly and remains readable.

Contact potential referees early and explain the opportunity and deadline. Where appropriate, share your current CV and research interests to help them understand the application’s focus. Give them adequate time to prepare a detailed recommendation. Use the organizer’s official website for submission and be cautious about third-party claims of guaranteed selection.

How to Prepare a Strong Application

As general writing advice, organize your CV so readers can readily follow your education and research experience. Present dates consistently and describe your work accurately, without overstating your contributions. Make relevant theoretical physics experience easy to locate. A clear presentation helps reviewers understand your background without unnecessary detail.

For the research interests statement, explain your interests precisely and connect them to your existing academic work. Use specific language rather than broad claims about enthusiasm or excellence. Ask a trusted academic colleague to check clarity, organization, and consistency with your CV. These are general preparation suggestions, not additional selection criteria.
