I am Professor of Theoretical Physics at the University of Oxford.
I work on a wide range of topics across string theory, cosmology, particle physics and astrophysics. My current research involves the use of X-ray observations of galaxy clusters to search for and constrain axion-like particles.
I am the author of Why String Theory? , a popular book explaining the who, what and why of string theory to a general audience. This was Physics World's 2016 Book of the Year, and is available from the publisher here .
My current CV is here .
