About the speaker

Emma Chapman is currently based at Imperial College London, where she is a Royal Society Dorothy Hodgkin Fellow. Emma has spent her research career in London so far, completing her PhD and first postdoctoral position at UCL before heading off to Imperial College for a Royal Astronomical Society fellowship. Her research is in the Epoch of Reionisation, a rather off-putting name for a very exciting time in our Universe – when the lights first switched on! As those first stars formed and starting flinging out high energy radiation, they formed bubbles of ionised hydrogen around them. We can observe this hydrogen today with radio telescopes and the race is on to make the first detection of the Epoch of Reionisation. Emma works mainly with the European telescope LOFAR based in the Netherlands.

Emma is passionate about trying to make astronomy and universities in general pleasant, safe places for everyone who works and studies there. Emma speaks regularly on the topic of harassment and bullying in physics in the media and a member of The 1752 Group, a research organisation coming to end staff-to-student sexual misconduct.
