In the UK, men hold 90% of senior positions in STEM. This means in a committee meeting of ten professors, at any given university in the UK, it is likely that only one female professor will be present in the room. Professor Arnold, who holds the Crum Brown chair of Chemistry at Edinburgh University, knows this tale too well. As recently highlighted by the BBC, to strike a balance, she has formed the Sci Sisters . Being part of this network, or ‘Scientific sisterhood’ means you can easily find nearby peers who are in similar positions and ready to talk about the issues you experience – even if it is just over coffee.
