Tom Engle will join a restructured DfID team on 21 March, taking charge of a 30-strong team at the department, overseen by international development secretary Hilary Benn.
Engle slots in below the new comms director position that will taken up by Transport for London head of media Paul Mylrea in April (PRWeek, 9 Dec 2006).
A restructure last year led to the research and evaluation elements of DfID's comms function being moved to other teams, leaving Mylrea's 80-strong division to focus purely on press and media work.
Engle joined the Natural History Museum in 2004 (PRWeek, 21 May 2004).
Before that he was head of external affairs at Jobcentre Plus, and also worked as a special adviser to David Blunkett when he was secretary of state for education and employment.
The Kensington museum - which is this week hosting the London Fashion Week Exhibition - is already hunting a replacement to run its 13-strong comms team.
Engle's role at the museum covers press, marketing and internal comms and his department is responsible for promoting the museum's scientific work as well as boosting visitor numbers.
