The HEC Montréal professor ranks 3rd in Canada and 43rd in the world in this list, based mainly on the Google Scholar h index. The index considers both the number of publications by a scholar and the number of times his or her work has been cited.

The Digital Bibliography and Library Project (DBLP), a website that publishes a catalogue of computer science bibliographies, was also used in creating this ranking.

Top 1000 Scientists 2019 gives Professor Laporte an h index of 121, with 59,376 citations recorded by Google and 349 papers in the DBLP catalogue.
