Murray will take over from John Thompson, who has been in the post since the academy was launched in 2006. "I am looking forward to guiding the academy into a dynamic stage of activity as we develop our role and relationships," he said.
"From a modest start, we have grown into a progressive group that enables creative thinking and research around good urbanism. In recessionary times, sustaining attractive resilient places is becoming more important but tougher to deliver."
Murray, a founding director of the academy who led its programme of events, was elected into his new role earlier this year. A handover ceremony will take place today at the Urbanism Awards.
At the awards, Professor Wulf Daseking, a city planner in Freiburg, Germany, will also receive the position of honorary academician of the academy.
