Susan Golombok is Professor of Family Research and Director of the Centre for Family Research at the University of Cambridge, and a Professorial Fellow at Newnham College, Cambridge. Her research has not only contributed to theoretical understanding of family influences on child development but also has addressed social and ethical issues that are of relevance to family life. She has pioneered research on lesbian mother families, gay father families, single mothers by choice and families created by assisted reproductive technologies including in vitro fertilisation (IVF), donor insemination, egg donation and surrogacy. Her research has challenged commonly held assumptions about these families as well as widely held theories of child development. The desire to obtain high-quality empirical data in order to examine the consequences for children of growing up in different family environments has been a major driving force behind her research, i.e. to shed empirical light on areas where people hold strong opinions, often without full knowledge of the facts. In addition to academic papers she is the author of Parenting: What really counts? and co-author of Bottling it Up, Gender Development, Modern Psychometrics and Growing up in a Lesbian Family. Her latest book is Modern Families: Parents and Children in New Family Forms published by Cambridge University Press.
