Personal profile
Research interests
I am an astrophysicist working in the Centre for Astrophysics Research (CAR) at the University of Hertfordshire. My main research interests are related to active galactic nuclei (AGN) - very bright regions at the centre of some galaxies that are thought to be associated with the supermassive black holes that live there. My current focus is on the properties of AGN that are detected at radio wavelengths, and I am involved in the LOFAR radio astronomy collabration and the Radio Galaxy Zoo: LOFAR project. I was awarded my PhD at The University of Sheffield in 2021 for investigating the properties of a particular type of these active radio galaxies (thesis title: "The optical morphologies and radio properties of HERGs with intermediate radio powers"), where I also obtained my Masters degree in Physics and Astronomy. I am also interested in the importance of galaxy interactions and collisions for triggering AGN.
