A senior London transport figure has joined Arup.
Isabel Dedring, currently deputy mayor for transport, will become global transport leader at the engineering firm on 21 March.
Arup said Dedring would have a role driving the firm’s “global transport agenda”.
Prior to landing her transport role at City Hall in 2011, she spent eight years as the mayor’s environment advisor. She also spent six years at Transport for London.
London mayor Boris Johnson said: “Isabel Dedring has been an indispensable member of my team and the absolute lynchpin behind the vast improvement across every aspect of transport services in London over recent years.
“She has made a colossal contribution to our city, overseen the successful delivery of major pieces of transport infrastructure and lobbied with great effect for more.
“Isabel leaves us with a world-class transport network that Londoners can be proud of and I wish her all the very best in her future career.”
Arup group chairman Gregory Hodkinson said: “At a time when rapid urbanisation and population growth drives the increasing demand for improved mobility, it is crucial that we implement smart and resilient transport solutions for the movement of people and goods.
“Isabel brings extensive experience of leadership in transport policy, planning and delivery, and I am looking forward to her helping us to drive the firm in exciting new directions.”
Dedring said: “New innovations in funding; the emergence of zero-emission technologies; the need for closer integration between planning and transport; the explosion of digital technology; and ever-higher public expectations from transport are just a few examples of the changes creating opportunities in this field. I look forward to working closely with colleagues to build on Arup’s outstanding reputation in this area.”
