Jane Lewis has been a key user of and advocate for evidence and implementation science in the UK for a number of years. Her earlier career was in evaluation and research dissemination before a combination of frustration and curiosity drove her into the warm embrace of implementation science. She was previously Head of UK Programme Development & Quality with Save The Children UK, leading on innovation, implementation, evaluation and scale-up strategies for SCUK’s UK programmes and prior to that held the position of Director of Implementation Support at the Colebrooke Centre for Evidence and Implementation. Previous to that she ran Research in Practice, supporting evidence-informed practice in children’s services in local government and NGOs. Her background is in research and evaluation: she led a research department at NatCen Social Research (one of the premier social policy research and evaluation centres in the UK) for many years, and then ran the research centre at the National Children’s Bureau (one of the UK’s leading NGOs in child and family services). As a member of CEI’s leadership team, Jane leads our work programme and team in the UK, as well as supporting our work in Europe, Australia and Singapore. She works across evaluation, evidence synthesis and active implementation support and relishes the opportunity to bring these together to improve services and support for children and families.
