I'm a Professor of Astronomy and Space Science at the University of Cambridge.
My research is mainly on trying to understand our universe around us. Aside from astronomy and space science, I’ve been very much engaged with science policy, particularly how modern technology can be controlled so that we can harness its benefits but avoid its downsides.
