Professor Stergios-Aristoteles Mitoulis, Professor at University College London (UCL), The Bartlett School of Sustainable Construction, visited the College of Architecture and Urban Planning (CAUP) at Tongji University for an exchange on resilient and sustainable urban environments.

During the visit, Professor Mitoulis met with Professor Xing Shi and Professor Ariel Peixian Li, along with their colleagues and students, to explore innovative approaches to transforming built environments through sustainability and resilience.

He expressed appreciation for the warm welcome and stimulating discussions, noting his interest in building future collaborations between Tongji University and UCL’s Bartlett School of Sustainable Construction.

This visit reflects his continuing efforts to advance international collaboration at the intersection of resilience, sustainability, and urban planning, aligned with the mission of MetaInfrastructure.

Shanghai, China — September 2025

Professor Stergios-Aristoteles Mitoulis, Professor at University College London (UCL), The Bartlett School of Sustainable Construction, delivered an invited lecture at Tongji University, Department of Geotechnical Engineering.

The lecture, titled “Sustained Resilience: Framing the Integration of Resilience and Sustainability in the Built Environment”, introduced the concept of sustained resilience as a lifecycle-oriented framework that bridges short-term resilience with long-term sustainability.

Professor Mitoulis delivered seven pathways — from deterioration and breakdown to proactive advancement and regulatory uplift — showing how cities and infrastructure can not only withstand disruptions but also learn, adapt, and evolve.

He expressed his gratitude to Professor Zhongkai Huang for the kind invitation and inspiring discussions, and to colleagues and students for their enthusiastic engagement and insightful questions.

This lecture reflects Professor Mitoulis’s ongoing contributions to advancing knowledge at the intersection of resilience, sustainability, and infrastructure digitalisation, aligned with the mission of MetaInfrastructure.

Beijing, China — September 2025

Prof. Stergios-Aristoteles Mitoulis, Associate Professor at University College London (UCL), The Bartlett School of Sustainable Construction, was invited to deliver a distinguished lecture at the Chinese Academy of Sciences, Institute of Geographical Sciences and Natural Resources Research, Beijing.

The lecture, titled “Wildland Urban Interface and Critical Infrastructure: A Missing Link in Wildfires Resilience”, addressed the vulnerabilities of the Wildland–Urban Interface (WUI) and presented a framework for strengthening infrastructure resilience across the wildfire cycle — before, during, and after events. Prof. Mitoulis highlighted the use of fragility curves and digital tools to inform future-ready standards in wildfire resilience.

He expressed gratitude to Professor Jianghao Wang for the invitation and warm hospitality, as well as to colleagues and students for their stimulating discussions and exchange of ideas.

Prof. Mitoulis emphasized the importance of international collaboration, noting that the engagement with the vibrant Chinese research community will pave the way for further joint work on resilience, sustainability, and the digitalisation of critical infrastructure systems.

Acknowledgements were extended to Dr. Yiming Xiang, Dr. Sotirios Argyroudis, and Dr. Stavros Sakellariou, alongside the ongoing support of the MetaInfrastructure initiative.

MetaInfrastructure is pleased to highlight a new open-access article published in Sustainable Development:

“Enhancing Sustainability and Resilience Against Natural Hazards of the Built Environment — State of the Art and Development of a Novel Framework.”

The paper introduces a transparent, practical two-step framework that unifies sustainability and resilience assessment across the full life cycle of buildings and infrastructure. It:

• incorporates social impacts alongside environmental and economic dimensions,
• accounts for performance evolution over time, not just a single snapshot,
• and supports proactive, risk-aware decision-making for policymakers, engineers, and asset managers.

As climate change intensifies natural hazards, the framework offers a structured path to reduce risk while advancing long-term sustainability goals.

Title: Resilience Models for Tunnel Recovery After Earthquakes

This work is the result of an exceptional collaboration with Tongji University’s world-leading engineering team, bringing together expertise to address a pressing global challenge:

How can we deliver more resilient tunnels to natural hazards?

Our research introduces—for the first time in the international literature—innovative resilience models that integrate engineering, data, and recovery planning to deliver faster, more robust post-disaster responses. These models can shape future infrastructure policy and practice, ensuring safer, more resilient cities worldwide.

We are pleased to announce the publication of our latest research in Results in Engineering, titled:

“Effect of deterioration on critical infrastructure resilience—Framework and application on bridges,”
authored by MetaInfrastructure group leader Prof. Stergios-Aristoteles Mitoulis and Prof. Davide Forcellini.

This study introduces a novel resilience assessment framework that explicitly incorporates ageing and deterioration in both the loss and recovery phases of critical infrastructure systems, with a focused application on seismic resilience of bridges.

Highlights of the research:

• The research highlights the direct integration of deterioration mechanisms in both fragility models and recovery processes.
• Differentiated resilience outputs across varying service lifespans (20, 40, and 60 years), reflecting environmental exposure and asset age.
• Development of realistic recovery curves for degraded infrastructure—addressing a critical gap in existing resilience models.

This paper has received early recognition, with 25 citations within two months of publication—demonstrating the relevance and potential impact of the proposed framework.
