The Laboratory of Digital Sciences of Nantes (LS2N) is composed of researchers working in the fields of Robotics, Computer Science, Computer Engineering, Industrial Engineering and Signal Processing corresponding to a total of around 500 people, of which 25% are women. In this laboratory, a Gender Equality and Diversity commission was created in 2019 and gathers today 34 people (65% women). This paper describes the efforts made by this commission since 2019 in order to evaluate, communicate about and improve the gender equality situation in the LS2N. The actions toward this end and discussed here include the proposition of a survey on gender inequalities early in 2020; the observation of women hiring process progress across eight years; the creation and maintenance of mentoring programs; and finally raising awareness among LS2N members through the organisation of seminars, conferences, listening groups and training. We also present the various challenges encountered and our current perspectives.
