WiSER (Centre for Women in Science and Engineering Research) at Trinity College Dublin (TCD) (Ireland) was established following a funding call from Science Foundation Ireland in 2005 aimed at addressing the under-representation of women in science, engineering and technology. The Centre aims to recruit more women and girls into STEM careers and education; to enable highly skilled women researchers to remain in STEM careers; and to encourage and assist top-level researchers to return to work following a career break. WiSER’s activities and practices are underpinned by the core value that scientific excellence is only achievable in an environment that supports, enables and sustains all outstanding researchers, regardless of gender. WiSER collects gender disaggregated statistics in TCD and reports on them annually to highlight gender gaps and to monitor progress. WiSER offers a range of practical professional development training to women academics and researchers working in STEM in TCD such as a mentoring programme, seminars which provide networking opportunities for women, WiSER academic writing group seminars and tips and information on how women can build their academic research profile via online tools and checklists and other supports. There is also information on work life balance and TCD policies and support for career breaks and flexible working. Funding for the Centre comes from the university (TCD). However, many of the WiSER activities have been funded through EU projects such as INTEGER.
