Portia's mission is to help women and men have the same opportunities for engagement and advancement in science, across all science disciplines, and to further the understanding and appreciation of the gender dimension in science knowledge making. Portia was established in 1997 by a group of female scientists working at Imperial College and incorporated as a not-for-profit company in 2001. The original motivation was to respond to the then UK government's concerns about under-representation of women in Science, Engineering and Technology. More lately, we have focused on the role of gender as a dimension of quality in research and innovation. The Gender Summits (www.gender-summit.com) were established as part of our genSET project in 2011. We work in international partnerships that expand the Summit across the world. We are delighted be part of partnerships bringing you regional Summits in Africa, South-Pacific and Europe in 2015.
