Examining academics 'engagement with non-academics in industry, public agencies and charities, this paper examines gender gaps between men and women. Using a large-scale survey of UK academics, we find that although there is difference between women and men in the commercial areas of engagement, with men being more active in this domain than their women colleagues of a similar age and experience and of the same rank, discipline, and university, this pattern is reversed for academic engagement with the third sector, with women more likely to engage with charities, regardless of career stage and research field. We explore the gendered nature of academic engagement, and discuss policy implications arising from it.
