Sanj Srikanthan will join disaster relief charity ShelterBox as its new chief executive in December.
He replaces Caroline White who has been interim chief executive since November 2018; she will be moving to another interim assignment.
Srikanthan is senior vice president for Europe and executive director for the UK at the International Rescue Committee (IRC); during a 10-year career at the crisis charity headquartered in New York.
He was emergency field director in an earlier role at the IRC, where he lead response teams in Mali, Syria, Lebanon and Turkey.
He has worked for the United Nations Office for the Coordination of Humanitarian Affairs, and was a captain in the British Army for over six years.
'Powerful clarity of mission'
Srikanthan said: "It will be a huge privilege to lead ShelterBox, an organisation with such a powerful clarity of mission – to turn despair into hope through shelter provision.
“Over the course of my career, I have seen first-hand the direct impact that quality emergency shelter can have in helping people begin to recover from disaster."
James Sinclair Taylor, chair at ShelterBox, said: "Sanj brings a wealth of humanitarian expertise to lead ShelterBox forward and develop a truly global organisation.
“Everyone here is excited to welcome him to the team, working together to give families a place to call home after disaster."
ShelterBox has its operational headquarters in Truro, Cornwall and its teams are currently working with communities in Cameroon, Paraguay, Somaliland and Syria.
