Education and career
Aardal is originally from Norway. She earned her Ph.D. in 1992 at the Université catholique de Louvain in Belgium. Her dissertation, On the Solution of One and Two-Level Capacitated Facility Location Problems by the Cutting Plane Approach, was supervised by Laurence Wolsey. Her dissertation won the second-place SOLA Dissertation Award of the Institute for Operations Research and the Management Sciences Section on Location Analysis.

Aardal was formerly a researcher at the Dutch Centrum Wiskunde & Informatica, and additionally affiliated with Eindhoven University of Technology since 2005. She moved to Delft in 2008.

She was elected to the 2019 class of Fellows of the Institute for Operations Research and the Management Sciences.
