Researcher

Sébastien Konieczny

Sébastien Konieczny is an AI researcher whose work applies logic to belief merging and reasoning with inconsistent information. He earned a PhD in computer science at Université de Lille 1 in 1999, joined CNRS at IRIT in 2001, and moved to CRIL in 2004. He directed the GDR IA from 2016 to 2023, became a EurAI Fellow in 2024, and served as the Hauts-de-France regional Fête de la science ambassador in 2025. As of October 2026, he leads the ANR-funded REVISE project at CRIL.

Timeline

  1. 1995–1999

    A computer science PhD

    He earns an MSc in computer science at Université de Lille 1 in 1996 and completes a PhD there in 1999.

  2. 1999–2001

    Teaching at EUDIL and Lens

    From 1999 to 2000, he works as a teaching and research assistant at EUDIL and LIFL. At IUT de Lens and CRIL, he teaches from 2000 to 2001.

  3. 2001–2004

    A distance-based merging framework

    At IRIT, Université Paul Sabatier, he joins CNRS as a research scientist in 2001. His work uses logic for AI. In 2002, he coauthors “Distance-based merging: a general framework and some complexity results” with J. Lang and Pierre Marquis; the paper sets out a general framework for distance-based belief merging and studies complexity results.

  4. 2004–2023

    Directing the GDR IA

    He moves to CRIL at Université d'Artois as a CNRS research scientist in 2004 and becomes a CNRS research director there in 2010. From 2016 to 2023, he directs the GDR IA on formal and algorithmic aspects of artificial intelligence.

  5. 2024

    A EurAI fellowship

    He is named a EurAI Fellow in 2024.

  6. 2024

    An AI guide for readers

    He coordinates the second edition of “L'intelligence artificielle. De quoi s'agit-il vraiment ?”, published by Cépadues in 2024 with GDR RADIA and Henri Prade. The book introduces artificial intelligence to general readers.

  7. 2025

    Hauts-de-France science ambassador

    He becomes the Hauts-de-France regional ambassador for Fête de la science in 2025. His public outreach covers AI, collective decision-making and truth discovery. His research addresses belief merging and inconsistency management.

  8. As of October 2026

    Leading the REVISE project

    He is a CNRS research director at CRIL and leads REVISE, selected for ANR funding in 2026.

  1. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes CNRS. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  2. Universities keep AI researchers for a median of 6 years, compared with 2 years at frontier labsIncludes CNRS. Across 15,811 dated work stays (6,529 people), median role tenure runs from 6 years at universities to 2 years at frontier labs. We compare all five organization types, starting decades from the 1970s to the 2020s, and the organizations that keep people longest.
  3. People shaping AI work at a median of 3 organizations over a career: 3 for university starters and institute and lab starters, versus 2 for company startersIncludes CNRS. Across 6,853 people shaping AI with a dated work role, we estimate a median of 3 parent organizations over a career (mean 3.6), comparing role groups, starting sectors and starting decades from the 1950s to 2020–2026.
  4. The top 10 organizations employed 22% of people shaping AI in 2025: 51% of company researchers and 21% of university researchersIncludes CNRS. We estimate the share of people shaping AI who worked at the top 10 organizations each year from 1955 to 2025, comparing concentration across companies, universities, and institutes and labs.
