Lindsey is the Centre Head of Quantitative Social Science in DSS. As a trained economist, her research interests focus on intergenerational transmissions, including intergenerational income mobility and intergenerational joblessness. Her previous research has considered the role of cognitive and non-cognitive skills, education and labour market experience in the transmission of income and work across generations. She has written a number of papers relating to educational inequalities including the impact of selective schooling systems on social mobility, understanding the improved performance of London pupils, and the characteristics and outcomes of those who undermatch in higher education. She also has a keen interest in the role of family background in access and progression within top professional jobs. Alongside her academic publications, Lindsey works closely with government and third sector organisations including the Social Mobility Commission.

She is currently PI on two ESRC grants: a Future Research Leader's grant, investigating intergenerational joblessness in an international context, and a Standard Research Grant examining intergenerational income mobility for women in the UK. She is also CI on a Nuffield Foundation grant on undermatch in higher education. From May 2019 she will be CI on a Nuffield Foundation grant on subject and qualification choices 16-19 and university outcomes. Alongside her funded projects, she is carrying out research considering parental investments and child outcomes, and working with a number of professional services firms to analyse the SES composition of their applications data.

Lindsey is a Research Fellow in the Education and Skills sector at the Institute for Fiscal Studies, and a Visiting Senior Research Fellow at the Centre for Analysis of Social Exclusion at London School of Economics.
