Geach conducts ground-breaking research into the evolution of galaxies (Geach et al. 2014, Nature, 516, 68; Geach & Peacock 2017, Nature Astronomy, 1, 795; Rupke, Coil, Geach et al. 2019, Nature, 574, 643) and has pioneered the use of unsupervised machine learning in astrophysics (Geach 2012, MNRAS, 419, 2633; Spindler, Geach & Smith 2021, MNRAS, 502, 985).
Jim is an astrophysicist specialising in galaxy evolution and observational cosmology, with an interest in cross-disciplinary and applied methods. With a degree in physics from Imperial College London and a PhD in astronomy from Durham University, Jim has nearly two decades of research experience at the forefront of his field, holding a Banting Fellowship at McGill University in Montreal and a Royal Society University Research Fellowship at the University of Hertfordshire, where he is a Professor of Astrophysics and Director of CoDIR. Jim has written two popular science books on galaxy formation and evolution, and is a co-founder of Aspia Space Ltd., a “NewSpace” company developing novel AI techniques for the downstream analysis of Earth Observation data.
