Professor Corran obtained her PhD in Pure Mathematics, On monoids related to braid groups, from the University of Sydney in 2000. She had a post as assistant lecturer at the University of NSW, Australia, in that year. In 2001 she was the recipient of an EPSRC grant to work on reflection groups at the University of Leicester, England. In 2002 she was awarded a two-year European Union Marie Curie postdoctoral award with the Centre National de Recherche Scientifique (CNRS) in Paris. In 2004, she took up a postdoctoral position at the Ecole Polytechnique Federale de Lausanne. She joined The American University of Paris in 2005.

Corran's mathematical research interests are in group and semigroup theory, particularly in terms of presentations and decision problems. She has been looking at reflection groups, braid groups, and Garside groups and monoids. Current projects include root systems for complex reflection groups and investigating new presentations for groups related to braid groups. She has published in Advances in Mathematics and the Journal of Algebra, among others.
