His research mainly concerns quantum gravity, black holes, general relativity, and supergravity.
Perry attended King Edward's School, Birmingham, before reading physics at St John's College, Oxford.
In these early years, he worked on several very influential papers on Euclidean quantum gravity and black hole radiation with Gary Gibbons and Hawking.
[3] In his final years in Princeton he worked with Curtis Callan, Emil Martinec and Daniel Friedan to calculate the low-energy effective action for string theory.
In 2010, his attention has focused on generalised geometry and the doubled formalism for string theory, extending these ideas to M-theory in collaboration with David Berman.
