Morrison takes up her job at the charity, which helps older people remain active and independent, on 1 March. She joins from the National Endowment for Science, Technology and the Arts, an organisation that promotes the application of innovative ideas, where she was deputy chief executive.
Before that, she was a policy adviser, first at the NCVO, then at the BBC.
She said: "There are more than 11 million older people in the UK. They want a voice in how their communities are shaped, choice in the services they need and control over their lives. The challenge for us is to review how best we can help them lead independent and fulfilling lives."
