MSCA DN RESILIOUS Candidacy 2026

What happens when the Internet fails?

We are bringing together 15 PhD researchers and a network of universities, research centres, and industry partners across Europe to investigate how we can make the Internet more resilient.

What happens when a submarine cable is cut? When satellites lose contact with one another? Or when a cyberattack disrupts the networks we depend on every day?

The Internet is remarkably resilient, but it is far from invulnerable. As our dependence on digital infrastructure grows, so does the need to understand where it is vulnerable, how failures spread, and what we can do about them.

These are some of the questions we want to explore in RESILIOUS.

We are bringing together 15 PhD researchers and a network of universities, research centres, and industry partners across Europe to investigate how we can make the Internet more resilient. The research spans satellite communications, underwater robotics, network security, autonomous systems, and Internet governance.

As part of RESILIOUS, you'll have the opportunity to explore challenging research questions, experiment with new ideas, and work alongside researchers and industry experts from different disciplines and countries.

We are recruiting 15 PhD researchers. If you are curious about how the Internet works, why it sometimes fails, and what we could do differently, have a look at our open positions. One of these questions might be yours to explore.

Who can apply?

We welcome applications from curious and motivated people from around the world.

You don't need to know everything about your chosen research topic before starting your PhD. We're looking for people who enjoy tackling difficult problems, asking questions, learning new things, and working with others.

Different positions call for different skills and backgrounds, so have a look at the individual vacancies to see which ones interest you.

Eligibility requirements

There are a few formal requirements under the Marie Skłodowska-Curie Actions (MSCA) programme:

  • No PhD yet: You must not already hold a doctoral degree at the time of recruitment.
  • Mobility rule: You must not have lived or carried out your main activity (work or studies) in the country where you will be recruited for more than 12 months during the 36 months before recruitment. MSCA exceptions may apply.
  • Open to all nationalities: You can apply regardless of your nationality.
  • University admission: You must meet the PhD admission requirements of the university associated with your position.

How to apply

Please submit your CV, copies of your Bachelor's and Master's degrees and academic transcripts, and a research statement of no more than 800 words.

About your research statement

We are not looking for a polished research proposal or a summary of everything you know about the topic. We'd like to understand how you approach an unfamiliar research problem.

Choose one specific question related to the position and explain why you find it interesting, what makes it challenging, and how you might begin investigating it.

We would also like you to describe one assumption you would question or one experiment that might prove your initial idea wrong. There is no single correct answer.

You are welcome to use AI tools to help with writing and language, but the research choices and reasoning should be your own. We may discuss your ideas during the interview.

Positions

Can satellite networks stay connected when things go wrong?

Resilient architectures for LEO mega-constellations

TU Delft, Netherlands · 36 months

Thousands of satellites are being launched into low Earth orbit, forming networks that could provide connectivity almost anywhere on Earth. But what happens when satellites fail or communication links suddenly disappear? Can the network reorganise itself, or could a few failures disrupt an entire constellation?

In this PhD, you'll explore how large satellite networks can be designed to withstand failures and adapt to changing conditions. You'll investigate how satellites connect, how disruptions affect the network, and how alternative connections can help keep communication running. The research will involve modelling and simulation, with opportunities to work alongside our partners at Lasting Software and Qascom.

What if satellites from different constellations could talk to each other?

Cross-operator interoperability for federated LEO satellite networks

Tu Wien, Austria · 36 months

Imagine if satellites operated by different companies could communicate directly with one another. Today, satellite constellations are largely designed as independent networks, often using different communication technologies. But what would it take to make them work together? Could a satellite from one constellation discover, connect to, and exchange data with a satellite from another?

In this PhD, you'll explore how to make communication between different satellite networks possible. You'll investigate how satellites can discover one another, negotiate communication links, and adapt to differences in their radio systems and orbital motion. The research will involve software-defined radios and experimental prototyping, with opportunities to work alongside our partners at TU Delft and VodafoneZiggo.

Can we make the Internet more resilient by rethinking how networks connect?

Economic models and resiliency metrics for the EU’s communication infrastructure

Queen Mary University of London (QMUL), United Kingdom · 36 months

The Internet is not a single network. It is made up of thousands of interconnected networks, operated by different organisations, each making its own technical and business decisions. But what happens when an important connection fails? Why do some disruptions affect millions of users while others go almost unnoticed? And could satellite networks help when terrestrial infrastructure is unavailable?

In this PhD, you'll explore how the structure of the Internet and the economic decisions behind it influence its resilience. You'll investigate how networks depend on one another, how disruptions spread, and how we can better measure the Internet's ability to withstand failures. The research will combine network analysis, modelling, and economic perspectives, with opportunities to work alongside our partners at Pometry and the Internet Society.

Can underwater robots spot trouble before an undersea cable fails?

Predictive robotic inspection for resilient undersea cable infrastructure

MARBLE, Croatia · 36 months

Undersea cables carry much of the world’s Internet traffic, yet the seabed is a difficult place to inspect. What if underwater robots could identify early signs of damage or interference before connectivity is disrupted? How can a robot tell the difference between an ordinary change on the seabed and something that needs attention?

In this PhD, you'll investigate how autonomous underwater vehicles can inspect cables and recognise potential risks. You'll explore how sonar and camera data can be combined to build useful views of underwater infrastructure, and how robots might decide where to look next. The work connects robotics, sensing, and data analysis, with research exchanges at AIR-RMLD and the University of Trento.
