I’m an architect and urban designer working in Arup’s urbanism and landscape team in London. I’ve spent most of my career working on innovative solutions to the multiple spatial, social, economic and environmental challenges faced by cities today. Cities not only have to provide affordable housing, education and employment, transport, energy, water and food for their citizens; they also have to make the transition to a more sustainable low-carbon economy and become more resilient to the consequences of climate change and disaster. In the course of helping tackle these issues, I’ve worked on masterplans for major projects such as Stratford City in London, helped Dublin to meet its future transport needs with a new underground railway, explored the potential of smart city development in Malaysia and China, and worked on a national food security programme. Of late, I have been focussing on how we can integrate food production with urban systems and how smart technology can create environmentally sound, enjoyable urban environments.
