Further Information about the speaker, his work, and the talk gathered by our SCASTRO Secretary/Talks Arranger, Mike Maunder and issued in his meeting reminder email heralding the talk:-

Ivan started his astrophysics career with a PhD studying pulsating stars at the University of Sydney before holding various posts in Australia and the US before taking up his post at Liverpool where as well as conducting research he teaches cosmology and data science.

Ivan's talk will focus on the analysis of galaxies as a population. This allows researchers to empirically track galaxy evolution since if demographics of galaxy populations are measured at different distances - we are viewing the universe at different epochs. Ivan will show how apparently unusual compact and low luminosity galaxies fit into this picture and show how we can average light emitted at different epochs to create a colour of the universe.
