Theoretical Physics

Behind great science, there's great administration. We provide the coordination, support and expertise that help CERN's people, projects and communities succeed every day.

Applied Physics at CERN plays a vital role in transforming theoretical concepts into tangible technologies that drive both scientific discovery and practical innovation. From developing cutting-edge particle detectors to contributing to global medical advancements, CERN's applied physicists are at the forefront of technology that changes the world.

From advanced materials to innovative processes, we develop the technologies that enable CERN's scientific and engineering achievements.

Creating an inspiring and welcoming environment for CERN's scientific community by managing and developing CERN's buildings and infrastructures.

Communication and stakeholder engagement drive the Organization’s efforts to build and maintain strong political, financial and public support for CERN’s scientific and societal missions.

Data powers discovery. We transform complex information into insights, intelligence and innovation that accelerate science and improve CERN's operations.

Powering the world's most advanced scientific facilities. We design, operate and innovate the electrical systems that make CERN's research possible.

Precision electronics are at the heart of every discovery. We design the intelligent systems that measure, control and capture the signals shaping modern physics.

CERN’s Experimental Physics challenges the limits of our understanding, transforming bold theories into high-energy collisions that reveal the universe’s deepest secrets. From designing experiments to analysing breakthrough data, our physicists push the boundaries of knowledge every day. Ready to turn theory into discovery?

A world-class research centre relies on more than science alone. We develop and manage the facilities, infrastructure and everyday services that enable CERN's community to work, collaborate and thrive.

Every investment in science deserves trust. We ensure that CERN's resources are managed responsibly, transparently and sustainably, supporting discoveries that benefit the world.

Playing a pivotal role in ensuring the well-being of our people and the sustainability of our operations.

People are at the heart of everything we do. We help foster an inclusive environment so talented individuals from around the world can contribute to CERN's scientific mission and perform at their best.

Software is crucial to CERN's mission of producing particle beams for physics experiments, coordinating thousands of devices through a sophisticated accelerator control system. Our engineers and technicians develop software across all layers, from embedded real-time systems to micro-service-based backend servers and user interfaces. We leverage mainstream, open-source technologies such as Linux, Docker, Kubernetes, Java, Python, and Kafka, ensuring our knowledge is broadly applicable beyond CERN.

Moving science forward takes more than ideas. We coordinate the flow of people, materials and equipment that keeps CERN's research and operations running smoothly.

Mechanical Engineering at CERN is crucial to advancing technology and enabling cutting-edge scientific discoveries. Our engineers design, build, and maintain sophisticated machinery, complex accelerator systems and experimental facilities that power some of the world’s most complex and impactful experiments.

Every breakthrough starts with the right partners. We connect CERN's scientific ambitions with industry, securing the goods, services and expertise that make discovery possible.

Security is essential to scientific excellence. We help create a safe, secure and resilient environment where people, research and international collaboration can thrive.

Innovation doesn't stop at the laboratory. We transform CERN's technologies and expertise into real-world solutions that create impact far beyond particle physics.
