Britain’s railways, roads, and flood defences rest on a vast network of engineered slopes — cuttings carved through hillsides and embankments raised across valleys, many of them built more than a century ago. As storms intensify and seasons grow less predictable, keeping this ageing infrastructure safe has become one of the defining challenges in UK engineering research. A new appointment at Loughborough University places one of the country’s leading specialists at the centre of that effort. Professor Alister Smith, Professor of Geotechnical Engineering in the School of Architecture, Building, and Civil Engineering, has been awarded a Royal Academy of Engineering Research Chair, giving him a national platform to work with Network Rail and Arup on climate-resilient infrastructure. This article explains what the award involves, why the underlying science matters, and what it means for engineers and students who want to follow a similar path.
A Prestigious Platform for Applied UK Engineering Research
The Royal Academy of Engineering’s Research Chairs and Senior Research Fellowships scheme exists to support engineering academics who lead ambitious, applied research in collaboration with an industrial partner. The scheme is funded by the UK Department for Business, Innovation, Science and Trade (BIST), and competition is intense: only five researchers were selected in this round.
Each appointee is expected to build a world-leading research group focused on translating cutting-edge engineering into real-world impact. The current cohort spans an impressive range — from assistive robots designed for future healthcare to scalable graphene quantum electronic devices. Professor Smith’s chair addresses a problem with arguably the widest public reach of all: the resilience of the physical networks on which everyday life depends.
For prospective postgraduate researchers, appointments like this offer a useful signal. They show where national funding bodies see long-term strategic need — and where research groups will be recruiting talented engineers in the years ahead. If you are considering a research career in civil engineering, it is worth reviewing the full list of appointments on the Royal Academy of Engineering research awardees page to understand the directions the field is taking.
The Challenge: Ageing Earthworks in a Changing Climate
The core of the new research programme is the UK’s ageing earthwork infrastructure. Earthworks are the engineered slopes created when transport routes cut into or build up soil: the cuttings that carry railways through high ground and the embankments that carry them across low-lying land. Structures of the same type also provide flood protection in many parts of the country.
Much of this asset base was constructed in the Victorian era or earlier, using compaction standards and materials that predate modern engineering codes. The soil within these slopes has been slowly strengthening — or weakening — for generations, and its condition is highly sensitive to water. Prolonged rainfall raises pore pressures and reduces the friction that keeps a slope stable; extended drought dries and cracks clay, leaving it vulnerable when heavy rain eventually returns.
Why Slope Failures Matter
When an embankment or cutting fails, the consequences ripple outward quickly. Landslips close rail lines, cutting communities off and triggering costly emergency works. Failures in flood embankments can inundate homes and farmland. Asset owners such as Network Rail already spend significant sums inspecting, monitoring, and remediating slopes, and the frequency of weather-related failures has been rising. Without better predictive capability, infrastructure managers face an unenviable choice between expensive precautionary interventions and reactive emergency response after failure.
Where Geotechnical Engineering Fits In
Geotechnical engineering is the discipline concerned with the behaviour of soil and rock — how ground supports structures, how water moves through it, and how it deforms or fails under load. It underpins foundations, tunnels, retaining walls, dams, and, in this case, the slopes that carry the nation’s transport network.
Professor Smith’s existing research focuses on monitoring and predicting the behaviour of soil and geotechnical systems through three complementary approaches: laboratory experimentation, field monitoring, and computational modelling. In practical terms, that means reproducing slope behaviour at reduced scale in the laboratory, instrumenting real embankments to measure how they respond to seasons and storms, and building numerical models that extend those observations to assets that cannot be instrumented directly.
That combination — physical evidence, field data, and simulation — is increasingly the template for modern infrastructure research, and it is precisely the skill set that employers such as Arup and Network Rail seek in geotechnical specialists.
The Research Agenda: Delivering Climate-Resilient Earthworks
The chair’s programme has two linked objectives. The first is to improve understanding of how weather drives the deterioration and eventual failure of earthworks. The second is to convert that understanding into practical tools: predictive models that forecast which assets are most at risk, and intervention strategies that allow engineers to act before failures occur.
This matters because infrastructure managers oversee thousands of individual slopes with finite budgets. Better prediction allows targeted spending — strengthening the small number of assets that genuinely need it, while avoiding unnecessary works elsewhere. The end goal is infrastructure that is not simply rebuilt after failure but designed, maintained, and adapted to remain serviceable under the climate conditions of the coming decades.
The Value of Industry Partnership
The collaboration with Network Rail and Arup is central to the design of the programme. Network Rail owns and operates the rail earthworks where many of the highest risks sit; Arup brings international consultancy experience in geotechnical design and risk management. Embedding industrial partners from the outset shortens the distance between research findings and deployment on the ground — a principle the Royal Academy of Engineering has deliberately built into the scheme.
“I’m delighted to have this opportunity to work with our excellent team at Loughborough University and colleagues at Network Rail and Arup to create innovative solutions for climate-resilient earthworks,” Professor Smith said of the award. “This research will help us better understand how earthworks respond to a changing climate and support the development of more resilient infrastructure.”
The National Engineered Slope Simulator: A National Asset on Campus
A key enabler for this programme already exists at Loughborough University. Professor Smith is Director of the National Engineered Slope Simulator (NESS), a facility built to test engineered slopes under controlled conditions. NESS allows researchers to reproduce years of weathering — cycles of wetting, drying, loading, and unloading — in compressed timeframes, generating data that would take decades to collect in the field.
Facilities of this kind are rare, and they influence where researchers choose to study and where industry turns for answers. For students, access to large-scale experimental infrastructure means hands-on experience with the equipment and measurement techniques that define contemporary geotechnical practice.
What Aspiring Engineers Can Take From This Appointment
For students and early-career engineers, the award offers several practical lessons about how influential careers in UK engineering research develop.
- Specialise in a genuine problem. Professor Smith’s work concentrates on a specific, nationally significant challenge. Deep expertise in one important problem is more valuable — and more fundable — than broad but shallow coverage of many topics.
- Combine methods. The programme joins laboratory work, field monitoring, and computational modelling. Engineers who can move fluently between physical testing and data-driven simulation are in particular demand.
- Build industrial relationships early. The chair is co-delivered with industry. Collaborations with employers such as Network Rail and Arup typically begin long before awards of this size, through placements, joint projects, and sponsored PhDs.
- Think in terms of impact. Selection for the scheme emphasises translating research into measurable outcomes. Framing research questions around real benefits for asset owners and the public strengthens both funding applications and career progression.
Practical Routes Into Geotechnical Engineering and Research
For readers inspired to pursue this field, the pathway is well established. Most geotechnical engineers begin with an accredited undergraduate degree in civil engineering, followed by a master’s specialisation in geotechnics or soil mechanics for those heading toward research or complex design work. Chartered status through a professional institution, such as the Institution of Civil Engineers, remains the recognised benchmark for practising engineers.
The research route continues with a PhD, typically three to four years, during which candidates develop specialist expertise and begin publishing. Postdoctoral fellowships and, ultimately, schemes such as the Research Chairs programme represent the later stages of an academic career. Along the way, skills in instrumentation, numerical modelling such as finite element analysis, and data science substantially widen the range of available roles.

The Broader Research Strength of Loughborough University
The award sits within a wider record of research strength. In the Research Excellence Framework (REF) 2021, over 90% of Loughborough’s research was rated as world-leading or internationally excellent. The university ranks eighth in the Complete University Guide 2027 and ninth in the Guardian University Guide 2027, placing it among a small group of institutions — alongside Oxford, Cambridge, and Imperial — that have held top-ten positions for more than a decade.
Its London campus, based on the Queen Elizabeth Olympic Park, extends this activity with postgraduate and executive education, and the university has been awarded eight Queen Elizabeth Prizes for Higher and Further Education. For prospective students, this institutional depth matters: research chairs attract further funding, leading facilities, and strong doctoral cohorts, all of which shape the quality of teaching and project opportunities available to students.
Looking Ahead: Infrastructure That Withstands the Climate of the Future
The UK’s earthworks will not be replaced wholesale; they will be managed, monitored, and selectively strengthened for decades to come. Research of the kind now funded through this chair is how that management becomes intelligent rather than reactive. Expect the coming years to bring new predictive tools, refined intervention strategies, and a growing evidence base shared between academia and industry.
For the engineering community, the message is clear: climate adaptation is no longer a niche specialism but a core requirement across civil infrastructure. For students choosing degrees, for graduates planning specialisations, and for professionals considering a return to study, geotechnical engineering sits squarely where that demand is growing fastest.
