Lumos is an international NGO (charity registered in England and Wales registered charity number 1112575) working to transform the lives of disadvantaged children in the European Region, where one million children live in large, residential institutions. Lumos believes that institutionalisation is a form of abuse, because research shows that, despite best intentions, institutions harm the health and development of children. The organisation works on seven different levels – from the individual child to international decision makers – to transform education, health and social care systems for children and their families; helping to move children move from institutions to family-based care. Lumos wants to end the systematic institutionalisation of disadvantaged children across Europe.
Lumos works in partnership with governments, professionals and carers, communities, families and children, to transform outdated systems that drive families apart. 
In 2005, Emma Nicholson and J. K. Rowling joined forces to address the problem of institutionalised and disadvantaged children in Eastern Europe. Together they formed an English charity (the Children’s High Level Group) and a Romanian charity (the Asociatia Children’s High Level Group).
In January 2010, Emma Nicholson resigned as Co-Chair of the board of the English charity. She continues as Chair of the Romanian charity (the Asociatia Children’s High Level Group), in which capacity she is furthering the work she began there and directing its resources to existing and new projects. The other board members of the Romanian Charity are Simona Andrei, Professor Kevin Browne, Mariela Neagu, Aneta Popescu-Black, Jonathan Scheele, Anthony Steen, Alin Teodorescu and Ion Tiriac.
