Michael Kramer
Michael Kramer, whose research uses the telescopes at Jodrell Bank Observatory, received the 2013 Herschel Medal from the Royal Astronomical Society. He joined The University of Manchester in 1999 and was appointed professor in 2006, before becoming Associate Director of the Jodrell Bank Centre for Astrophysics from 2007-2009. Kramer is currently Director of the Max Planck Institute for Radio Astronomy in Bonn, Germany, but retains his appointment in Manchester. He also holds an honorary professorship at the University of Bonn. He is an international leader in the field of pulsars - extremely compact neutron stars weighing as much as the Sun but only the size of a city, and spinning at rates up to hundreds of times per second. The extreme gravity of these neutron stars makes them excellent laboratories for testing Einstein's theory of gravity, General Relativity. Kramer was the first to detect geodetic precession; an effect of the curvature of space-time predicted by General Relativity.
