This is an interview with Professor Lynda Birke (University of Chester, UK), one of the key figures of feminist science studies. She is a pioneer of feminist biology and of materialist feminist thought, as well as of the new and emerging field of hum-animal studies (HAS). This interview was conducted over email in two time periods, in the spring of 2008 and 2010. The format allowed for comments on previous writings and an engagement in an open-ended dialogue. Professor Birke talks about her key arguments and outlooks on a changing field of research. The work of this English biologist is typical of a long and continuous feminist engagement with biology and ontological matters that reaches well beyond the more recently articulated ‘material turn’ of feminist theory. It touches upon feminist issues beyond the usual comfort zones of gender constructionism and human-centred research. Perhaps less recognized than for instance the names of Donna Haraway or Karen Barad, Lynda Birke’s oeuvre is part of the same long-standing and twofold critique from feminist scholars qua trained natural scientists. On the one hand, theirs is a powerful critique of biological determinism; on the other, an acutely observed contemporary critique of how merely cultural or socially reductionist approaches to the effervescently lively and biological might leave the corporeal, environmental or non-human animal critically undertheorized within feminist scholarship. In highlighting the work and arguments of Lynda Birke, it is hoped here to provide an accessible introduction to the critical questions and challenges that circumvent contemporary discussions within feminist technoscience as theory and political practice.
