We caught up with Jon Hays, from Queen Mary's University, and John Andrew from Advanced Power Technology.

More about both interviewees

Jonathan Hays is a Professor of Physics at Queen Mary University of London, where he is the head of the Particle Physics Research Centre. His research interests rest mainly with high energy particle physics, having been involved with research at the Large Hadron Collider for many years on the CMS and ATLAS experiments and at the Fermilab Tevatron before that. His main focus now is on low background experiments measuring neutrinos and searching for dark matter.

Alongside this, he has had a strong involvement in large-scale computing for over two decades as a user, developer, provider and now as Science Director of STFCs IRIS Federation - that coordinates and provides access to large-scale compute and data services across the science remit of STFC.

He is also Project lead for the National Federated Compute Services NetworkPlus Project that aims to provide a community driven roadmap for the future of a truly national joined up computing and data service serving users across the broad UKRI portfolio. Sustainable computing is a key part of this and he has been involved in multiple projects investigating how to achieve this through measuring, monitoring, and mitigating the impact of our scientific endeavours on the environment.

Queen Mary University of London, a research-intensive Russell Group university based in East London, is one of the top universities in the world. The University climbed 35 places in two years in the QS World University Rankings and is now ranked 110th in the 2026 rankings.

It is also a top 100 global university and top 10 UK university for the second year running in the 2025-26 US News and World Report Best Global Universities rankings, and is ranked 24th in the world for the quality of its research and 11th in the world for international outlook.

At Queen Mary University of London, there is a strong belief that a diversity of ideas helps achieve the previously unthinkable. Throughout the University’s history, it has fostered social justice and improved lives through academic excellence. It continues to live and breathe this spirit today, not because it’s simply ‘the right thing to do’ but for what it helps be achieved and the intellectual brilliance it delivers.

The University’s reformer heritage informs its conviction that great ideas can and should come from anywhere, an approach that has brought results across the globe, from the communities of East London to the favelas of Rio de Janeiro.

Queen Mary University of London continues to embrace diversity of thought and opinion in everything it does, in the belief that when views collide, disciplines interact, and perspectives intersect, truly original thought takes form.
