Rebecca Murray-Watson is a PhD student in the Space and Atmospheric Physics Group at the Department of Physics, Imperial College London, joining in October 2020. She is also affiliated with the Science and Solutions for a Changing Planet Doctoral Training Partnership at the Grantham Institute for Climate Change and the Environment. Her project, supervised by Dr. Edward Gryspeerdt and co-supervised by Dr. Helen Brindley, investigates aerosol-cloud interactions in Arctic clouds. Understanding the degree to which aerosols influence cloud physical properties, and therefore their net radiative effect, is essential to understanding the surface energy budget. This is particularly important in a warming Arctic. There is significant variation between model estimates of the strength of the forcing associated with aerosol-cloud interactions. This project hopes to address this uncertainty by using state-of-the-art satellite observations and other data to constrain the impact of aerosols on these Arctic clouds.

Prior to joining Imperial, Rebecca studied for an MSc in Environmental Modelling at University College London. Her dissertation, supervised by Professor Jan-Peter Muller, investigated the long-range transport of aerosols produced by the 2019/2020 Australian wildfires and their effects on the microphysical properties of clouds. She also holds an MSci in Natural Sciences (Chemistry) from the University of Cambridge, where she studied the structure and reactivity of organo-copper complexes with Dr. Sebastian Pike.
