Vlado Keselj

Vlado Keselj is a Dalhousie computer science professor whose AI work links natural language processing, authorship attribution and large language model reasoning. As a high school student in Yugoslavia, he won a bronze medal at the 1987 International Mathematical Olympiad, then earned degrees at the University of Belgrade and the University of Waterloo. His 2003 paper with Fuchun Peng, Nick Cercone and Calvin Thomas presented n-gram author profiles for authorship attribution. Keselj served as program co-chair of the Canadian AI conference in 2010, received CAIAC's Distinguished Service Award in 2019 and launched Dalhousie's Master of Digital Innovation program in September 2020. In 2026, he coauthored a study of token log-probability instability in large language model reasoning; as of October 2026, he is a professor and MDI Program Director at Dalhousie and teaches Natural Language Processing.

Timeline

  1. 1987

    An Olympiad bronze medal

    As a high school student in Yugoslavia, he wins a bronze medal at the International Mathematical Olympiad in 1987.

  2. 1994–2002

    Three computer science degrees

    He earns a BSc at the University of Belgrade in 1994, an MMath at the University of Waterloo in 1997, and a PhD there in 2002.

  3. 2003

    N-gram author profiles

    In 2003, he coauthors “N-gram-based Author Profiles for Authorship Attribution” with Fuchun Peng, Nick Cercone and Calvin Thomas. The paper presents Common N-gram Analysis (CNG), a method for character n-gram authorship attribution.

  4. 2010

    Canadian AI conference co-chair

    He serves as program co-chair of the Canadian AI conference in 2010.

  5. 2019

    CAIAC Distinguished Service Award

    He receives the CAIAC Distinguished Service Award in 2019.

  6. September 2020

    Launching the MDI program

    He launches Dalhousie's Master of Digital Innovation program in September 2020.

  7. 2026

    Detecting LLM reasoning failures

    In 2026, he coauthors a study on token log probabilities as an instability signal for large language model reasoning. The study reports that the signal predicts wrong answers on GSM8K and HotpotQA.

  8. As of October 2026

    Professor and MDI director

    As of October 2026, he is Professor of Computer Science at Dalhousie University and MDI Program Director. In Fall 2026, he teaches Natural Language Processing.

From the biography.

  1. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes Dalhousie University. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  2. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes Dalhousie University. 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.
  3. The median h-index is 48 at universities and 14 at frontier AI labsIncludes University of Waterloo. The median h-index is 48 at universities and 14 at frontier AI labs. We compare publishing careers, recent citations, dual appointments and job moves across 2,420 university researchers and 308 frontier-lab researchers.
  4. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes University of Waterloo. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
