The former boss of the Young Women's Trust has taken the top job at the Centre for Ageing Better on an interim basis.
Carole Easton is taking over from Anna Dixon, who announced in March she would step down this month.
Easton will lead the charitable foundation until a permanent replacement is found.
Her previous roles include spells as interim chief executive of Refuge, interim joint chief executive of the British Lung Foundation and chief executive of the Young Women’s Trust.
Easton also brings experience as a non-executive director, trustee and chair to the role, the Centre for Ageing Better said.
She is a board member of Advance, a charity that works with women who have experienced domestic abuse and those who have committed crime or are at risk of offending.
Easton said: “The work of the centre has demonstrated the benefits and the importance to individuals and to society of ensuring that people can have a good later life.
“I am keen to support and sustain the excellent work of the charity whose mission is to guarantee that a good later life is an aspiration that can be shared by everyone in the UK,” she added.
