Our work is now moving decisively from setup to delivery, with momentum building as ARIA enters its next chapter.
We announced Kathleen Fisher as our next CEO, joining us in February 2026. A world-class technologist, Kathleen brings deep technical leadership and a proven record of turning audacious research into reality, positioning ARIA’s programmes to deliver breakthroughs with the power to transform the world.
Evidence of our growing pace can be seen through the launch of the first programmes from our second cohort of Programme Directors – Precision Mitochondria, Sustained Viral Resilience and Enduring Atmospheric Platforms. We also saw the first major pivot to one of our programmes – Safeguarded AI – in response to the pace of frontier AI progress.
Alongside this, we published three new programme theses – Scaling Trust, Accelerated Adaptation, Massively Scalable Neurotechnologies – and launched a new opportunity space – Collective Flourishing.
We’ve continued to experiment in order to understand how best to catalyse our programmes into impact. In October, we launched an exploratory funding call to assess the current capabilities and potential of AI Scientists – autonomous systems that could transform how breakthrough research happens.
Our Activation Partners have also expanded their activity, from Renaissance Philanthropy’s inaugural Ember cohort to Venture Café’s expansion in Edinburgh and Manchester, and Cambridge Neuroworks’ Blue Sky Proof-of-Concept Fund.
The next quarter will see the arrival of our new CEO, alongside new programmes and the final opportunity space from our second cohort of Programme Directors, as we continue to strengthen the delivery and impact of ARIA’s work.

This quarter has seen significant developments at ARIA, as we evolve both the strategic vision and operational foundation needed to support breakthrough research at scale across the UK.
Critically, we conducted our search for a new CEO to lead the agency through its next phase, building on the foundations established over the last three years: a world-class executive and operational team, 16 visionary Programme Directors, and a community of over 200 funded research teams, Activation Partners, and collaborators.
In the last quarter, we continued to deliver on our priorities at pace, with our second cohort of Programme Directors significantly expanding our surface area for breakthroughs. We've launched 3 new opportunity spaces – Manufacturing Abundance, Engineering Ecosystem Resilience, Trust Everything, Everywhere – and published 5 programme theses – Universal Fabricator, Precision Mitochondria, Sustained Viral Resilience, Perpetual Flight – as we continue to back ambitious, edge of the possible R&D.
Beyond programmatic activity, September saw two key initiatives from our Activation Partners kick off: Pillar VC's Encode: AI for Science Fellowship, connecting AI talent with leading science labs, and Renaissance Philanthropy's Big if True Science Accelerator (BiTS), training scientists to build R&D efforts beyond single-lab scale. Later in the month, we launched Innovator Circles, an initiative designed to support individuals to convene their own technical peer groups, creating space in the R&D ecosystem where peers can push each other further and discuss ideas that could form the basis of future breakthroughs.
Following the reappointment of Matt Clifford as ARIA Chair in September, Q3 will see us announce the appointment of our new CEO, starting the leadership transition from a place of confidence and continuity, whilst we continue to strengthen the impact of our work and research communities through new partnerships, programmes, and funding opportunities.
- See the data
This quarter, significant developments signal our growing momentum: our second cohort of Programme Directors (PDs) are now in place, opening up bold new opportunity spaces from Sculpting Innate Immunity, Bioenergetic Engineering to an expanded Scoping Our Planet – and backing a new wave of Creators across Safeguarded AI, Synthetic Plants, Exploring Climate Cooling and Robot Dexterity.
We’ve also strengthened our leadership and the organisation behind it, welcoming Ant Rowstron as our inaugural Chief Technology Officer, and three new Non-Executive Directors with entrepreneurial experience across science and innovation – key steps in building ARIA”s ability to support breakthrough R&D at scale.
Meanwhile, in another clear sign of momentum, our Activation Partners are beginning to show what’s possible: Cambridge NeuroWorks has launched its first Frontier Fellows programme and Renaissance Philanthropy has introduced its UK Horizons initiative – helping pave new routes to talent and impact.
The next quarter will see us deepen these partnerships, launch five more opportunity spaces, and continue to grow our Creator network, building the conditions for breakthrough research to thrive. You can find out more about our activities and vision for the future in our 2025 Corporate Plan.

In our second year, we’ve begun to scale the ambition we set out in year one — extending our model, growing our portfolio, and deepening our commitment to long-term, transformative science and engineering. We launched our first set of seven programmes, and multiple seed calls, allocating more than £400 million in funding to the R&D ecosystem over the next three to five years. This work backs research aimed at breakthroughs ranging from catalysing a new generation of major crops that are more productive, resilient, and sustainable, to reimagining safety standards for transformational AI – all fundamental leaps toward technologies that seem intractable today, yet could prove critical for the future of UK industries. Our portfolio now includes over a hundred projects across universities, start-ups, and private organisations.
We also launched our Activation Partners initiative — partnerships with nine deeply technical, entrepreneurial organisations, from world-class research labs to cutting-edge science accelerators. They’ll play a vital role in developing talent, accelerating routes to market, and creating the conditions to help ensure the breakthrough R&D we fund translates into real-world impact.
With our second cohort of Programme Directors in place from April, we’re expanding into new scientific domains — broadening ARIA’s reach and unlocking breakthroughs with the potential for outsized societal and economic impact.
- See the dataARIA was created to be bold and agile, focusing on long-term transformation rather than quick wins. In our first year, we have built a strong foundation supporting that mandate: building a dedicated team, robust operations and infrastructure, and developing a new approach to funding R&D aimed at catalysing breakthroughs. Over the course of our first year, we developed seven opportunity spaces – areas we believe are ripe for discovering new technologies that seem intractable today but could prove critical for the UK long-term. These spaces span climate science, neurotechnology, AI and more. From these opportunities spaces, we launched our first two funded programmes – Scaling Compute and Safeguarded AI – and first set of opportunity seed awards in Nature Computes Better. Throughout this period we have prioritised engagement with experts across the R&D ecosystem. Through workshops, public calls for feedback, and open solicitations, we’ve invited input to help us consider different directions and surface new ideas – on the shape of our research programmes, as well as ARIA’s approach and operations.

home central heating? Surely, this only benefits the fossil fuel industry?
2. Sea water is known to have high levels of untreated sewage draining into it everyday. Surely seeding with sea
water is feeding the same sewage into our atmosphere and ultimately into our lungs?

"Why aren't these experiments restricted to unpopulated areas of the UK instead of towns and cities? Seeding over large woodland or moorland areas for example would cause less side effects for human health and safety. This was not detailed in your response.
Do you agree that any actions which cause extra use of home central heating systems are detrimental and should obviously be avoided? This was not confirmed in your response.
What specific form will the 'meaningful public engagement' take with Aria to allow the UK public to give feedback and objections to 'side effects' in real time? There are already mass respiratory problems amongst the UK population to which they have no redress or pathway to complain. This requires more detail for the public's peace of mind.
What measures are taken to ensure any and all sewage content is removed from seawater that is used for cloud seeding? This is not detailed in your previous response.
