In conversation with Christine Watson.

Christine J. Watson is Professor of Cell and Cancer Biology at the University of Cambridge. Christine obtained her Bachelor's (honors) degree in Biochemistry at the University of Glasgow in 1975 and, after a soujourn in Glauco Tocchini‐Valentini's lab at the Institute of Cell Biology, Consiglio Nazionale delle Ricerche in Rome, she undertook a PhD in Molecular Genetics at Imperial College London. During her PhD, she looked at differences in gene expression between differentiated and undifferentiated embryonal carcinoma stem cells, inspiring an early interest in gene expression and cell fate determination. Between 1986 and 1992, Christine undertook three postdoctoral research positions that took her from London back to Scotland, where she was first introduced to mammary gland biology through her work with John Clark at the Roslin Institute in Edinburgh. During her time in the Clark lab, Christine identified a factor – later shown to be STAT5 – that binds to the promoter of the milk protein gene β‐lactoglobulin. This prompted further work identifying the key role played by the STAT family of transcription factors in mammary gland development. Shortly afterwards, Christine became a group leader at the Roslin Institute and later relocated to the University of Edinburgh to collaborate with Andrew Wyllie. This led to her recruitment to the University of Cambridge in 1998, where she has remained to date. Over the last two decades, the Watson lab has focused on elucidating the mechanisms underlying lineage commitment of mammary stem and progenitor cells and the regulation of cell death in involuting mammary gland. In this interview, Christine discusses her research highlights and provides a glimpse into her personal interests, as she moves towards retirement. [ABSTRACT FROM AUTHOR]
