The war in Ukraine is often marked by specific dates, like February 24, 2022 – the day of the full-scale invasion. But for many Ukrainians, that February never really ended. For me, then a 22-year-old master’s student in construction engineering, that day shattered everything I understood about my future. I was glued to my phone, refreshing news updates in a frantic attempt to make sense of the chaos.
The distant echoes of explosions rumbled through the city, shaking windows and setting off endless car alarms. Air raid sirens wailed, their sound slicing through the early morning stillness. Outside, people hurried past with suitcases, their faces pale and tense, while others lined up at pharmacies and ATMs, their hands trembling as they stocked up on essentials.
My family and friends sent frantic messages (Are you safe? Are you leaving? What do we do?) but no one had an answer. Fear settled in like a second skin, thick and suffocating. The streets, once familiar, now felt unrecognisable, transformed by the weight of uncertainty.
We were all touched by the war, including my family. My father, who is a scientist and professor of Mykolaiv University of Shipbuilding, voluntarily joined the military forces to fight for Ukraine and give my family the possibility to work and study while the war raged outside.
Meanwhile, my hometown, Mykolaiv – previously a strategically important shipbuilding and port city on the Black Sea – became a key stepping-stone for Russian forces on the road to Odesa. It is very close to currently occupied territories and the frontline.

Controlling access to the city and its bridges was crucial in the battle for Ukraine. The destruction of these bridges cut off vital supply routes, leaving Mykolaiv isolated and struggling to hold the line. What were once ordinary crossings became symbols of survival, as the city fought to stay connected and withstand the siege.
As my home was attacked, I realised something fundamental: bridges were not just engineering projects. They were lifelines.
Engineering hope
Rebuilding bridges and roads is about more than repairing physical structures; it is about restoring security, economic stability and vital connections between communities. A collapsed bridge isolates people from essential services, disrupting supply chains and deepening vulnerability. The war has exposed just how critical Ukraine’s infrastructure is for survival.
Mykolaiv is one of the hardest-hit regions. According to the Ukrainian government, more than 20 bridges were destroyed or severely damaged by Russian attacks, including the Inhul Bridge, a vital artery for the city.
The Snihurivka Bridge, another key crossing, was also wiped out, leaving thousands stranded without reliable access to healthcare and supplies. For months, humanitarian aid and commerce were forced onto alternative, unreliable routes, further isolating communities. The reconstruction of key bridges in my home region has allowed life to resume, but the scale of the challenge across the country remains immense.

Elsewhere, the destruction has been just as devastating.. The Irpin Bridge, north-west of Kyiv, which once carried 40,000 vehicles a day, became a symbol of both loss and survival. Ukrainian forces had to destroy the bridge to stop Russian advances on Kyiv. Thousands of civilians fled across its wreckage under fire.
Science: a light in the dark
Fast forward to the autumn of 2022. Ukraine’s power grid was under relentlessattack. Entire cities were plunged into darkness. I sat at my desk in Lviv, in western Ukraine, where I have been working on my PhD thesis. My laptop battery was draining and a single candle flickered beside me. I was writing a research paper on strengthening methods for buildings and infrastructure. Yet, all around me real infrastructure was collapsing, making my work feel disconnected from reality.

The city had endured weeks of missile strikes targeting critical infrastructure and power cuts became part of daily life. Simple tasks like boiling water for tea, charging a phone, or even sending an email became unpredictable challenges. The hum of generators filled the streets and people lined up at charging stations trying to stay connected. The darkness wasn’t just outside, it seeped into everything, a constant reminder that the war was never far away.

At that moment, a question struck me: what if science could help rebuild Ukraine? Could research, something that had once felt so theoretical, actually make a difference in the aftermath of war?
My supervisor introduced me to BridgeUkraine: a research alliance of people focused on rebuilding Ukraine’s critical infrastructure. It was founded by two leading experts in disaster recovery and engineering: Stergios-Aristoteles Mitoulis, the head of structures at the University of Birmingham’s School of Engineering and Sotirios Argyroudis, reader of infrastructure engineering at the Department of Civil and Environmental Engineering at Brunel University.
The project aimed to not only repair what was damaged but to build better infrastructure: homes that are more resilient, more sustainable and ready for future crises. Mitoulis recalled that the whole idea for BridgeUkraine was born out of a deeply personal moment:
I first thought of BridgeUkraine when I spoke with my former MSc student, Marat Khodzhaiev, who was in Ukraine when the war started. He was stranded in his house and at risk of missing the opportunity to graduate from his MSc course in the UK. All bridges around him had collapsed, there was no escape route. His wife was pregnant at the time. That call made me realise the urgent need, not only to rebuild infrastructure, but also to support and empower Ukrainian engineers to build their future. BridgeUkraine became more than just a research alliance, it became a mission that ensures that Ukraine’s recovery will be driven by its own people, equipped with the best knowledge and tools to rebuild their country.
The KSE Institute estimates that more than 300 bridges across Ukraine require urgent reconstruction, with damages exceeding US$2.6 billion. But this isn’t all about infrastructure; it is about securing Ukraine’s independence and ensuring that its economy and society can function even under the most difficult conditions. Every bridge rebuilt is a step toward recovery, a restored connection between families and communities, and a symbol of resilience.
To address these challenges, rebuilding Ukraine’s infrastructure cannot follow conventional methods. The sheer scale of destruction demands a new approach, one that not only restores what was lost but strengthens the country for the future.
At BridgeUkraine, we are developing solutions that prioritise resilience over quick fixes. Instead of rebuilding vulnerable structures, we are integrating sustainable materials, climate-adaptive engineering, and strategic planning to ensure that Ukraine’s transport networks are built to last.
Rebuilding fairly and efficiently
A comprehensive assessment conducted by the government of Ukraine, the World Bank Group, the European Commission, and the United Nations estimates that the total cost of Ukraine’s reconstruction and recovery stands at approximately €506 billion (US$524bn) over the next decade. This underscores the necessity for continued and enhanced international support to address the extensive needs arising from the conflict.
There are no academic guidelines on how to rebuild after such destruction. What is the most effective way to approach reconstruction in this context? We quickly came to the realisation that conventional methods were too slow and rigid to address the urgent and widespread damage.
Our research team wanted to re-imagine how to rebuild infrastructure and homes that are resilient to future challenges, from war-related destruction to climate-induced disasters. As Mitoulis told me:
Rebuilding infrastructure is not just about restoring roads and bridges, it’s about rebuilding lives. Our approach is centred on people, ensuring that the infrastructure is designed by Ukrainians, for Ukrainians. It must not only reconnect communities but also support economic recovery and long-term resilience.
But such ethical reconstruction must be inclusive, sustainable and community-driven, ensuring that those who depend on infrastructure have a say in how it is rebuilt.
Reconstruction must be a participatory, creative effort – one that rebuilds cities with beauty and meaning, connecting them to their past while preparing for the future. Too often, post-war recovery efforts have been dictated by external donors, prioritising short-term economic gains over long-term resilience.
People like me, who have grown up in these places, understand the culture, the rhythm of daily life, and the importance of preserving identity as well as buildings. We want to see our cities restored in a way that reflects our history and spirit.
For example, in post-second world war Warsaw, reconstruction efforts initially ignored the city’s historical character in favour of Soviet-style urban planning. It was only through the persistence of local architects and historians that parts of the Old Town were painstakingly restored to reflect their original designs.
Ukraine cannot afford such myopic, profit-driven decision-making. Instead, it must empower local communities, integrating their knowledge, needs and skills into the reconstruction process.

This vision started to take shape through workshop discussions with experts in geography and urban planning. Everyone agreed on the need for an adaptable transportation system where modular designs and relocatable, prefabricated bridges (like the Mabey bridge in US) could respond to evolving demands and disruptions.
Similarly, at the ReBuild Ukraine 2024 conference leading engineers, policymakers and researchers showcased groundbreaking technologies designed to accelerate reconstruction while reducing long-term environmental and economic risks (for example, nature-based solutions, 3D-printing, Virtual Reality and Building Informational Modelling).
Revolutionising damage assessment with AI, radar and satellite imagery
But to effectively plan for recovery and reconstruction, it’s crucial to first accurately characterise the damage. A clear picture of what has been destroyed allows for smarter decisions, prioritising the most urgent repairs and using resources effectively.
Our latest research, published in Automation in Construction, introduces a faster, more precise way to assess damage to key infrastructure, particularly bridges. Bringing together expertise from a large multidisciplinary team, we developed a new approach that combines satellite images and radar and artificial intelligence to swiftly and accurately analyse damage.
This technology allowed us to assess the condition of bridges remotely, without having to be onsite in dangerous or inaccessible areas. By providing rapid, data-driven insights, our method helps ensure that reconstruction efforts start where they are needed most, speeding up recovery and making rebuilding efforts more effective.
We tested this approach on numerous bridges in the Irpin region of Ukraine, and the results were striking. It significantly improved both the speed and accuracy of damage assessments. Using Sentinel-1 SAR images (radar satellite images from the European Space Agency’s Copernicus program), crowdsourced data (photos and reports from people on the ground), and high-resolution imagery, we developed a comprehensive approach for damage detection and classification.
This approach works on multiple levels: it provides a big-picture view of damage across entire regions while also zooming in on specific structural issues in individual bridge components. By combining satellite data with detailed images, our method makes damage assessments more precise, faster and safer, ensuring that reconstruction efforts focus on the most critical areas first.
These findings can play a crucial role in damage and needs assessment such as those conducted by the World Bank.
Sustainable infrastructure
In war zones, destruction often affects vital humanitarian and evacuation corridors, making it essential to prioritise reconstruction based on factors such as the national importance of a bridge, its role in border crossings, and its impact on social services.
For instance, the failure of a bridge could disrupt emergency response efforts, further complicating recovery.
But rebuilding after a disaster is also an opportunity to create something stronger, smarter, built to last – and with a sustainable focus.
@kathryn_moskalyuk
Given Ukraine’s commitment to net-zero emissions and resilience, we expanded our research [and published a study] which introduced an innovative model for rebuilding infrastructure that can withstand future hazards while minimising carbon emissions. At its core, the model features a “smart prioritisation system” that helps decision-makers allocate resources effectively. It assesses key factors such as repair urgency, community impact and long-term durability, ensuring that rebuilding efforts provide the greatest benefits where they are needed most.
For example, when assessing damaged structures, the system prioritises projects that will provide the most long-term benefits. That might mean restoring energy systems to prevent future blackouts or repairing bridges that serve as key evacuation routes and economic lifelines.
As Stanislav Gvozdikov, deputy director of Euro-integration Process at Ukraine’s State Road Research Institute, told me: “Every bridge we restore, every road we reopen, isn’t just about infrastructure, it’s about restoring life, reconnecting families and ensuring that communities have the resilience to withstand whatever comes next.”
This is already a reality near my home town, Mykolaiv, where newly rebuilt bridges have restored transport links and also revived local economies, giving people hope for the future.
But no one rebuilds a country alone.
The UK-Ukraine 100-year agreement, announced in February 2025, underscored a deep commitment to Ukraine’s security, economic resilience, and post-war reconstruction. The partnership recognises the importance of cooperation between the UK and Ukraine to strengthen technological innovation and to increase collaboration in transport more widely.
I’ve also had the privilege of working with some of the brightest minds in the field, including more than 50 practitioners, consultants, academics, institutions and international bodies. This alliance of experts was united by a shared vision: to change the way the world approaches post-war reconstruction.
A key part of this mission is training engineers, equipping them with the latest knowledge in damage assessment, resilience-based and people-centred design and international standards to lead Ukraine’s reconstruction.
We come from different backgrounds – engineering, economics, policy, humanitarian efforts, and governmental bodies. But we all share the same motivation in wanting to help our country.
Leading researchers from Ukraine specialising in AI technologies, infrastructure engineering, sustainable and energy-saving buildings or climate change, are also members of BridgeUkraine. AI-specialist, Ivan Izonin has spoken passionately about how he believes that the collaborative efforts we have started “will lay the foundation for large-scale scientific projects that will be pivotal in post-war reconstruction…”. While Natalya Shakhovska , also a specialist in AI, recalled: “My activity in the BridgeUkraine alliance gave me the opportunity to align my research to critical infrastructure assessment, enabled by my AI modelling…Today I really feel included, I understand that my expertise is helping [my country’s recovery]”
Another enthusiastic Ukrainian researcher, Khrystyna Myroniuk, who specialises in building physics, told me how the collaboration had given her the opportunity to continue her “research on sustainable housing solutions for Ukraine”.
Stopping the brain drain
One of the most critical challenges facing Ukraine today, aside from the physical destruction, is the brain drain – the mass exodus of skilled professionals who left the country in search of safety and better opportunities abroad.
This trend has had a significant impact on the country’s ability to rebuild. Engineers, architects and other highly trained specialists have long been a pillar of Ukraine’s development. But the war has forced many to leave, with no clear path back to contribute to the reconstruction effort. BridgeUkraine is helping to reverse this trend by offering a compelling reason for these skilled professionals to return.

Our engagement with Ukrainian engineers then sparked another idea: what if we trained local professionals to apply our expertise, equipping them to drive this transformation within their engineering communities?
This vision became the foundation of the Empower Ukraine programme, through which, over 5,000 engineers and scientists will be trained in European (Eurocodes) and international design standards.
This ensures that Ukraine’s recovery is driven by its own people, equipped with the latest global knowledge. By bridging the knowledge gap and integrating the best methods and ideas from across Europe, Ukraine can position itself as a leader in resilient infrastructure design.
Our research was taken up by the Ministry of Restoration of Ukraine. Stanislav Gvozdikov collaborated with us to launch a joint programme of Continuing Professional Development seminars for engineers designed to help them stay up to date with the latest knowledge and skills in their field. To date, our expertise has been shared with over 1,500 Ukrainians.
Argyroudis emphasised to me how critical the role of engineers will be in Ukraine’s reconstruction, saying: “It’s about rebuilding Ukrainian identity as a country.”
The ultimate goal is to build a culture of innovation and self-reliance among local professionals who have the expertise and passion to drive this change.
Professionals can now contribute to projects and be part of a larger community of practice, which brings together engineers, academics and international partners.
I am, personally, incredibly proud to have had the privilege, over the past two years, to help empower Ukrainians to develop world-leading research that accelerates their country’s recovery.
Shaping tomorrow
My hometown, Mykolaiv, still bears the scars of war. Returning there, I saw firsthand what was lost. But also what could be rebuilt. War has taken, and continues to take so much, but it has also forged a new generation of engineers who understand that our profession is no longer just about calculations and designs. It is about resilience, survival and national recovery.
Three years ago, I would have imagined a very different career for myself. But today, I know that engineering is more than my profession, it is my mission.
I am committed to ethical and inclusive infrastructure recovery in Ukraine, because science must be the foundation of national resilience. Ethical reconstruction must prioritise people over profits, creating systems that empower and strengthen communities.
Ukraine’s recovery is about setting a global precedent for post-conflict reconstruction. Our research, training programs and commitment to innovation are laying the groundwork for a stronger, more connected Ukraine, offering a paradigm shift to the war-torn world. Because rebuilding is about more than replacing the past. It is about creating a future that can withstand whatever comes next.
