Elke Roediger joined the University of Hull in September 2015. She studied physics and astrophysics at the Christian-Albrechts-University of Kiel in Germany and at the University of Glasgow in Scotland, and was awarded the degrees of Diplom-Physikerin and MSc in astronomy and astrophysics, respectively. In 2005, she was awarded a PhD in astrophysics by the Christian-Albrechts-University of Kiel. Since then Elke held positions as a postdoctoral researcher at the Jacobs University Bremen and the Hamburg University Observatory, and had several short-term appointments as a Visiting Scientist at the Harvard-Smithsonian Center for Astrophysics. 

Elke's research covers the growth and evolution of galaxy clusters, the evolution of cluster galaxies, and plasma properties of the intra-cluster gas. Her research combines numerical simulations with observations in local and international collaborations.


Elke studies the evolution, dynamics, and properties of galaxy clusters and galaxies in them. Recent observations show a wealth of structure in clusters and cluster galaxies that goes beyond what can be explained by analytic estimates or simple toy models. Elke and her collaborators run numerical simulations of cluster mergers and galaxies falling into clusters, and compare their predictions to multi-wavelength observations by the world’s best telescopes.
