October 9, 2025

More than 20 members of the HEC Montréal community are featured in a ranking that considers the international influence of scientists across all fields.

The ranking was compiled by a research team from Stanford University and the Dutch publisher Elsevier.

It is divided into two lists: one based on citations and impact indices for the year 2024, and the other for the past 25 years.

The current faculty members of HEC Montréal who appear in this year's ranking are:

This group also includes professors Pierre Hansen, who passed away in 2025, and Jean-Charles Chebat, who passed away in 2019.

Alain Haurie, an affiliated professor, also appears in this ranking.

Several retired faculty members are also featured:

• Henri Barki
• Alain D’Astous
• Ann Langley
• Gilbert Laporte

It is worth noting that the latter, along with senior researcher Danny Miller, are ranked in the global top 10 of their respective fields (operational research and management).
