George Horner is a PhD student in the Space and Atmospheric Physics (SPAT) Group at the Department of Physics, Imperial College London. He is affiliated with the Science and Solutions for a Changing Planet Doctoral Training Partnership at the Grantham Institute for Climate Change. His project, supervised by Dr. Edward Gryspeerdt and co-supervised by Dr. Helen Brindley, investigates the effects of aerosols on convective clouds. There is clear evidence for an aerosol impact on convective clouds, but it has not been scaled up to a global estimate of the radiative forcing. New satellite retrievals and geostationary imagers provide the opportunity to do this. This has the capability to create an important constraint for global models.
George obtained an MSci in Physics from University College London prior to joining Imperial. His dissertation, supervised by Prof David Waters, investigated the effects of helium exposure on photomultiplier tubes used in the SuperNEMO particle accelerator.
