For PhD Candidate Brandy Alger, one of the most rewarding parts of her research is seeing what can happen when a community comes together around a good idea.

That idea recently became a reality in Invercargill, with Brandy helping to pilot Borrow a Builder, an initiative designed to help older residents make simple earthquake safety improvements inside their homes. The idea came from one of the older community members involved in Brandy’s research: why not “borrow” a builder to help people make their homes safer?

Through the pilot, local builders visited 13 older residents’ homes and helped with practical earthquake-safe actions, including strapping hot water cylinders, securing heavy furniture and installing magnetic latches on cabinets.
Each resident also received an emergency grab bag starter kit, along with practical items and preparedness resources to help them continue getting prepared.

The pilot brought together a number of organisations and local businesses, with Master Builders leading the programme. Age Concern New Zealand Southland helped identify and connect with residents who could benefit from the initiative. Emergency Management Southland supported the initiative from the beginning and contributed items for the emergency kits. The Invercargill New Zealand Red Cross Disaster Welfare Support Team also visited each home beforehand with residents, helping identify which earthquake safety actions needed to be completed.

"It was pretty special to see an idea from the community become something that brought so many different people together and resulted in safer homes for the wider older community," Brandy says.

📢 A very warm welcome to our Erskine Fellow, Associate Professor Janille Smith-Colin. She is a faculty member in the Department of Civil and Environmental Engineering at Southern Methodist University (SMU) and will be here until the end of November. Janille is hosted by Tom Logan and Matthew Hughes.

A big thank you to the Erskine Fellowship for making visits like this possible and helping UC stay connected with leading academics and universities around the world.

Janille’s scholarly vision is to advance the integration of sociotechnical perspectives into civil infrastructure planning and design. Her research in transportation systems develops context-responsive approaches to reduce mobility gaps, address infrastructure inequities, and support the equitable and culturally responsive adoption of emerging mobility technologies. Using quantitative, spatial, and data-driven methods, her work examines how infrastructure systems interact with the people and communities they serve.

In the classroom, she challenges students to broaden conventional engineering analysis by grappling with complex socio-infrastructure problems and integrating resilience and sustainability into engineering decision-making. Her commitment to teaching was recognized with SMU’s 2022–2023 Golden Mustang Award for excellence in teaching, curricular innovation, and scholarship that advances student learning. She teaches undergraduate and graduate courses across Civil and Environmental Engineering and SMU’s Sustainability + Development Program (S+DP), including Sustainable Transportation and Civil Infrastructure Systems. Janille is also a licensed Professional Engineer (PE).

In her free time, she enjoys strength training, with a particular interest in weightlifting.

👏👏👏

We're delighted to share that Professor Santiago Pujol has been selected to receive the Wason Medal for Most Meritorious Paper from the American Concrete Institute (ACI).

The award recognises Professor Pujol and his co-authors, Rémy D. Lequesne and Chungwook Sim, for their paper, “The Urgent Need for Increased Robustness of Buildings in Highly Seismic Regions”, published in the January 2025 issue of Concrete International, Vol. 47, Issue 1, pp. 49–55.

The paper examines trends between measures of building robustness and building performance observed following 15 earthquakes. It compares approaches used in countries that favour stiffer structures with those that use less-stiff structures, and considers what these observations mean for the future of reinforced concrete practice.

The Wason Medal for Most Meritorious Paper was established in 1917 by Leonard C. Wason, a past president of ACI, and has been awarded continuously since then. It is awarded each year to the author or authors of the most meritorious paper published by the Institute, with all original papers eligible for consideration.

Professor Pujol and his co-authors will be recognised at the ACI Fall 2026 Concrete Convention in Atlanta, Georgia, USA, during the “Paper Awards Presentation Session: Published in 2025.”

Congratulations Professor Pujol and his co-authors for this well-deserved recognition!

For PhD candidate Jose (Enrique) Andrade Gamboa, an earthquake during his undergraduate studies changed the direction of his career.

Enrique moved to Mexico City to study Civil Engineering at the National Autonomous University of Mexico (UNAM). During his first semester, the city was hit by its most devastating earthquake since 1985. It also happened on the same date, 19 September.

Witnessing the damage made Enrique interested in structural engineering, as a way to help increase the resilience of the city he had just seen being devastated.
Today, his PhD research under the supervision of Dr Ke Jiang and Professor Santiago Pujol is focused on concrete structures that use glass fibre reinforced polymer (GFRP) bars instead of traditional steel reinforcement.

“GFRP is basically a strong plastic bar reinforced with glass fibres,” Enrique explains. “The idea is simple: can we use something that does not rust instead of steel?”

His research focuses on an important question for earthquake engineering: whether using GFRP reinforcement will cause a structure to displace more during an earthquake.

The research could help make structures more durable, particularly in corrosive environments. Understanding how much displacement to expect could also help engineers make better decisions when using displacement-based design.
One of the most interesting aspects of the research for Enrique has been looking back through almost a century of research and finding that many of the challenges engineers face today were recognised long ago.

His inspiration comes from some of the great names in structural engineering and beyond.
“As Timothée Chalamet once said, I am inspired by the greats,” Enrique says. “I feel as inspired by Emilio Rosenblueth, Mete Sozen, and Hardy Cross as I am by Michael Jordan or Michael Phelps.”

For Enrique, these figures share something important: their lives were dedicated to saving lives and securing the future, especially in structurally and socially vulnerable communities.

“That is the kind of work I want to contribute to.”

Professor Santiago Pujol, Dr Ana Sarkis, Dr Julián Rincón and Assistant Professor Edgar Chacón travelled to Venezuela to study and document the effects of the earthquakes that struck on 24 June 2026.

The reconnaissance mission brought together researchers associated with UC, including former UC PhD candidates, Ana Sarkis and Dr Julian Rincon, and was sponsored by QuakeCoRE, NZSEE and UBC. The team collaborated with researchers from Colombia (CEER and SCI) and Venezuela (UCV and CVC).

The team also carried out earthquake reconnaissance in Colombia, where they saw first-hand how structural design and retrofit decisions can affect building performance. In both countries, there were clear examples of retrofitted buildings alongside similar unretrofitted buildings, with markedly different levels of damage.
The main objective of the reconnaissance mission was to obtain quantitative information on building structures and their response to ground shaking, to identify trends between building properties and building response.

Venezuela has been using building codes for seismic design for more than 60 years. The quality of construction in Venezuela is on par with that of prosperous countries, as Venezuela had a very strong economy for decades thanks to its abundant oil reserves. Most multistorey buildings in Venezuela have reinforced concrete (RC) structures, similar to New Zealand.

A preliminary analysis of the information collected suggests that, beyond shaking intensity, a critical factor that played a role in the Venezuelan disaster was the lack of robustness of the buildings. This lack of robustness is common in buildings not designed to limit building sway within tight ranges. Very few countries, Japan and Chile for instance, impose tight limits on earthquake building sway. The data obtained will help determine how more stringent building standards can help reduce earthquake damage in New Zealand.

📢 We're pleased to welcome Xiaotian Yan from Southwest Jiaotong University (SWJTU), where he has studied and conducted research in Transportation Engineering since his undergraduate studies. He is supported by the China Scholarship Council (CSC) to conduct research here at UC.

Xiaotian's research focuses on shared mobility, especially its integration with public transport. This includes network optimisation and simulation design.

" I am interested in this area because I hope to develop travel options that are fast, efficient, and seamless, while reducing operating costs and improving passengers’ travel experience."

He will be here for one year under the supervision of Dr Wai Wong. During his visit, Xiaotian will further investigate the integration of emerging mobility services with public transport, as well as travellers’ willingness to use multimodal transportation.

Outside of research, Xiaotian enjoys hiking and working out. He's looking forward to experiencing life in New Zealand, exploring the South Island, and enjoying its beautiful scenery.

👏👏👏

Congratulations to Dr Paul Horne, who has been named one of the five recipients of the Society of Fire Protection Engineers’ (SFPE) 2026 Global 5 Under 35 Award.

The international award recognises emerging leaders making significant contributions to fire protection engineering and the wider profession. Paul has been recognised for his work across research, practice, teaching and service, particularly his research into the fire performance of timber structures.

His work looks at the competing demands of timber buildings, including how to balance seismic performance with structural stability under severe fire conditions involving combustible mass timber. Addressing these challenges is an important step towards expanding the use of mass timber construction in New Zealand.

The recognition follows Paul being named New Zealand’s Emerging Professional Fire Engineer of the Year last year. He will join the other 2026 recipients at the SFPE Annual Conference & Expo in Atlanta in October.

Congratulations, Paul, on this well-deserved global recognition!

Earlier Warnings for Natural Hazards Could Save Lives, But May Mean More False Alarms 🌋🌋🌋

Lecturer Dr Alberto Ardid and his colleagues have published new research in Nature Communications exploring the socio-economic value of data-driven forecasts for natural hazards, using volcanic eruptions as a test bed. Read here - https://www.nature.com/articles/s41467-026-77242-4

Earlier warnings can give people and authorities more time to act, but they may also come with more false alarms. The challenge is therefore not necessarily to build warning systems that are never wrong, but to build systems that support better decisions when the consequences of being wrong are asymmetric. Read here: https://theconversation.com/earlier-volcano-warnings-could-mean-more-false-alarms-but-they-could-also-save-lives-290430

As a society, we may sometimes need to accept more false alarms if doing so substantially reduces the risk of catastrophic loss. This has important implications for how we evaluate forecasting systems: the objective should not simply be to minimise false positives, but to support better decisions under uncertainty.

Using volcanic eruptions as a case study, the team explored the trade-off between how early a model can anticipate an eruption and how many false alarms it produces, placing these forecasts within a socio-economic decision-making framework.

The research has also been shared with a wider audience through The Conversation.

We're so happy to share that two of our PhD candidates - Mahdi Mokham and Zahir Azimi are among the nine finalists for the Building People Awards 2026! 👏👏👏

The big-picture question of Mahdi's idea is how to make New Zealand homes more energy-efficient and warmer with lower costs. He's working on creating a relatively large, detailed dataset of residential buildings in New Zealand, which is going to help create more efficient policies, designs, and urban energy assessments that contribute to better-performing, healthier, and more sustainable housing in New Zealand.

Zahir's research is on "Addressing New Zealand’s Housing Shortage Through Fast-Setting, Steel-Fibre-Reinforced 3D Concrete Printing.”

The concept focuses on developing a fast and practical 3D concrete printing approach that could contribute to more resilient, affordable, and low-carbon housing in New Zealand. With the use of conventional truck mixers, standard concrete can be transported and pumped as usual. Near the printing nozzle, a specially formulated fast-setting agent and micro steel fibres can then be introduced as secondary additions. This approach could bridge conventional concrete production and delivery methods with advanced 3D concrete printing technology, enabling rapid setting and enhanced structural performance without requiring an entirely new concrete supply chain.

Congratulations to you both - We’re so proud to see you among the finalists and wish you all the very best!

📢 We're very pleased welcome to Miss Jinyao Zhao who arrived last week from Guangzhou, South China University of Technology (SCUT). Her previous academic background was in Mathematics and Probability and Statistics, and she will now be conducting research in transportation. She was awarded a CSC (China Scholarship Council) to conduct her research here.

Jinyao’s current research focuses on Urban Air Mobility (UAM), which explores the use of electric vertical take-off and landing vehicles (eVTOLs) for passenger transport within and around cities. She became interested in this area because of becoming curious about how emerging transport technologies can complement existing systems and improve the efficiency and accessibility of urban travel.

Here for one year, she will be working with Transportation group and supervised by Dr Yi Wang. During her visit, Jinyao will investigate infrastructure planning and operational strategies for UAM, with a particular focus on eVTOL range, vertiport configuration, and airport shuttle applications.

Apart from her studies, she enjoys Pilates and swimming. Since arriving in Christchurch, she is hoping to spend more time outdoors, try new activities, and explore the South Island.
