The fourth LGBT+ STEMinar was held at the Institute of Physics in London on Friday 11 January, bringing together LGBT+ researchers across science, technology, engineering and maths to share their research and discuss challenges facing the LGBT+ community. Started in 2016, the LGBT+ STEMinar series aims to showcase work from diverse fields and encourage collaborations between different departments, universities, companies and subjects, while giving greater visibility to LGBT+ researchers. This year’s event was the biggest yet, with over 150 researchers from across the world gathering at the new London office of the Institute of Physics.
