Associate Professor of Astrophysics, University of Portsmouth

I am an associate professor of Astrophysics at the University of Portsmouth's Institute of Cosmology and Gravitation, an honorary associate professor at University College London (UCL), and a research associate at the American Museum of Natural History. I study different types of transients – astrophysical phenomena that change on human timescales. I mostly work on supernovae (the explosions of stars) and tidal disurption events (bright flares caused by stars being shredded by supermassive black holes). My books include [Supernova](https://mitpress.mit.edu/9780262543149/supernova/) and [Galaxies](https://mitpress.mit.edu/9780262548755/galaxies/)._
