Profile
Dr Helen Freeman is a Postdoctoral Research Fellow at the University of Leeds. After studying physics at the University of Manchester she completed a Masters in environmental energy and engineering before moving to Leeds to do her PhD in radiation damage of nuclear graphite.
In 2016 Helen moved to Berlin to work at the German research centre for geosciences (GFZ), returning to the UK in September 2018 to join the Crystallisation in the Real World EPSRC Programme Grant. Since 2011, she has used transmission electron microscopes (TEMs) to analyse a range of samples, from radioactive material in nuclear reactors to environmental remediating minerals and hydrated clays. She has a particular interest in analysing dynamic processes using in-situ (S)TEM, with her main focus at the University of Leeds being in liquid-cell and cryo TEM.
