I lead the global Buildings Retrofit team from Arup’s Cardiff office. I am passionate about the potential for retrofitting existing structures to help tackle a range of issues – climate change in particular. Some of the retrofit projects I’m most proud of being involved in are the Terminal Building at London’s Stansted Airport, the Loyola Law School Casassa Building in Los Angeles, and the National Waterfront Museum in Swansea, Wales.

I’ve  lectured and speak frequently on building retrofitting at institutions and conferences around the world. I am the Chair of Wales’ Low/Zero Carbon Hub and a Member of the Welsh Government Construction Sector Panel.

My other interests include the environmental physics of large volume enclosures in hot arid regions, which I’m currently undertaking a research project on.
