Professor Isobel Hook

Professor of Astrophysics

Research Overview

My research is focused on using distant supernovae for cosmology, specifically to measure the effects of Dark Energy in the universe. I am also involved in several future telescope projects including the European Extremely Large telescope (E-ELT), the Large Synoptic Survey Telescope (LSST), the 4-metre Multi-Object Spectroscopic Telescope (4MOST) and ESA's Euclid mission.
