Dr Catherine Reynolds, 37, a scientific researcher at Imperial College, poses for a picture at her laboratory in London, Britain February 22, 2017. "Women are very well represented at junior levels in Biological Sciences research. At a senior level it is still true that there are fewer female professors in science, but the gap is slowly closing," Reynolds said. "More policies that promote flexible working and that support staff in taking career breaks (both men and women) are an essential way in which it is possible for employees, especially those with young families, to realise their full potential in the workplace."
