Toby Wiseman is a professor of theoretical physics at Imperial College London. He completed his PhD in cosmology at the University of Cambridge and continued as a junior research fellow in Stephen Hawking’s general relativity research group. He then spent three years at Harvard University as a postdoctoral researcher before returning to the UK as a lecturer at Imperial College. His research specializes in fundamental aspects of gravity and black holes. He is particularly interested in understanding space-time and gravitation at the smallest and largest scales and also how string theory combines Einstein’s theory of gravity with quantum mechanics. He enjoys scientific outreach and has appeared in the media discussing the science of black holes and gravity.
