Ruth Gregory

Gregory earned her PhD from the Department of Applied Mathematics and Theoretical Physics at Trinity College, Cambridge in 1988, writing a thesis on "topological defects in cosmology" supervised by John M. Stewart. ==Career==

Gregory held postdoctoral appointments at the Fermi National Accelerator Laboratory and Fermi Institute in the University of Chicago, before returning to Cambridge for a five-year research fellowship. She was appointed Professor of Mathematics and Physics at the University of Durham in 2005. She serves as a managing editor of International Journal of Modern Physics D. ==Research==

Her research centres on the intersection of fundamental high energy physics and cosmology. She is best known for the Gregory–Laflamme instability, describing an instability of black strings in higher dimensions. ==Awards and honours==

Gregory was given the 2006 Maxwell Medal and Prize by the Institute of Physics for her contributions to physics at the interface of general relativity and string theory, in particular for her work on the physics of cosmic strings and black holes. In 2011 she received the Royal Society Wolfson Research Merit Award to study Time and Extra Dimensions in Space. ==Selected publications==
