Dr. Greg Brown is an astronomer working at the Royal Observatory Greenwich. In his time in research at the University of Warwick, he studied some of the largest explosions in the Universe and the supermassive black holes hiding in distant galaxies. Combining a love of science, comedy and acting, Greg moved into science communication, where he has been eliciting polite applause, anguished groans and the occasional approving nod from his audiences ever since.
