Melinda Mills (MBE, FBA) is Director of the Leverhulme Centre for Demographic Science and Professor at the University of Oxford and Nuffield College. She works in the area of combining a social science and molecular genetic approach to the study of behavioural outcomes, with a focus on human fertility, socioeconomic differentials and the labour market. In 2019, she was awarded £10 million from The Leverhulme Trust to Direct and build the interdisciplinary Leverhulme Centre for Demographic Science. She was the PI of the ERC SOCIOGENOME (2014-2019) project and continues this line of research in an ERC Advanced Grant (CHRONO) (2019-2026) and Editor-in-Chief of the European Sociological Review (2012-2017). She has led genome-wide association studies (GWAS) of human reproductive behaviourdetailed review of all GWAS to date, and also studies diversity in genetics, assortative mating, labour market uncertainty and chronotypes. In addition to this book, she has a similar book on survival and event history analysis in R. Mills has published 7 books and around 100 articles across multiple disciplines including: Science, Nature Genetics, Proceedings of the National Academy of Sciences, Human Reproduction Update, JAMA Psychiatry, Proceedings Royal Society B, Annual Review of Sociology, Human Reproduction, European Journal of Human Genetics, European Sociological Review, Journal of Marriage and Family, Social Forces, Behavior Genetics.

Nicola Barban is a Reader (Associate Professor) at the Institute for Social and Economic Research (ISER) at the University of Essex and a co-Director of the ESRC Research Centre on Micro-Social Change (MiSoC). He is also an Associate Fellow at Nuffield College, University of Oxford. In 2020 he started the 5-year ERC Consolidator Project GENPOP (Genes, genealogies and the evolution of demographic change and social inequality). He did his PhD in Statistical Sciences at the University of Padova, Italy. Before moving to Essex, he worked as Senior Research Associate at the University of Oxford on the ERC SOCIOGENOME project and as a postdoctoral researcher at the University of Groningen. He has published in a variety of topics in journals such as Nature Genetics, Nature Human Behaviour, American Sociological Review, Social Science and Medicine, Sociological Methods and Research, International Migration Review and European Journal of Population.

Felix Tropf is Assistant Professor of Social Science Genetics at École Nationale de la Statistique et de L'administration Économique (ENSAE) and Center for Research in Economics and Statistics (CREST) in Paris. His current research interests include (the genetics of) fertility and mortality, natural and artificial selection, social stratification, mental health, as well as various substantial and methodological questions surrounding genetic confounding and gene-environment interaction. His research has been published in Demography, Nature Genetics, Nature Human Behaviour, JAMA Psychiatry, Proceedings of the National Academy of Sciences and Population Studies. Tropf also received the European Demography Award for best PhD Thesis and previously worked on the ERC SOCIOGENOME project. Webpage:
