Freidel received his PhD in 1994 from the École normale supérieure de Lyon (ENSL) in Lyon , France. He stayed at ENSL officially as a research scientist for 12 years, until 2006. During that time he also held a postdoctoral position at Pennsylvania State University in State College , Pennsylvania , United States from 1997 to 1999 and an adjunct professor position at the University of Waterloo in Waterloo, Ontario , Canada from 2002 to 2009. In 2006 he joined Perimeter Institute as its ninth faculty member.
Between 2004 and 2006 Freidel has coauthored a series of papers on the Ponzano-Regge model, a spin foam model of 3-dimensional quantum gravity .[3] In 2007 he introduced, with Kirill Krasnov, a new spin foam model for 4-dimensional quantum gravity which has become known as the Freidel-Krasnov model.[1]
In 2011 Freidel published a paper with Giovanni Amelino-Camelia , Jerzy Kowalski-Glikman and Lee Smolin introducing the principle of relative locality , a proposed generalization of the principle of relativity in which different observers see different notions of spacetimes.[4] Between 2013 and 2015 he published a series of papers with Robert Leigh and Djordje Minic introducing a new formulation of string theory , metastring theory , which implements the notion of relative locality in a precise way and introduces a new notion of modular spacetime .[5]
