Researcher

Bogdan Grechuk

Bogdan Grechuk is a mathematician whose AI research studies error correction and advanced mathematical reasoning. He won an International Mathematical Olympiad gold medal in 1997 and a silver medal in 1998, and competed for Moscow Institute of Physics and Technology in 2002. His work includes mathematical risk research, a 2021 book on recent mathematics, and FrontierMath, a benchmark he co-authored to evaluate AI reasoning. As of October 2026, he is an associate professor at the University of Leicester and works with Surge AI on mathematical problems that challenge current models.

Timeline

  1. 1997–1998

    Gold and silver at the IMO

    He wins a gold medal in 1997 and a silver medal in 1998 at the International Mathematical Olympiad.

  2. 2002

    Competing for MIPT

    In 2002, he competes for Moscow Institute of Physics and Technology at the International Mathematics Competition for University Students.

  3. 2009

    Chebyshev inequalities

    In 2009, he co-authors “Chebyshev Inequalities with Law-Invariant Deviation Measures” with Anton Molyboha and Michael Zabarankin while affiliated with Stevens Institute of Technology.

  4. 2011–2014

    Leicester teaching and risk theory

    In 2011, he begins lecturing at the University of Leicester. In 2013, he co-authors a study of risk sharing in cooperative games with Anton Molyboha and Michael Zabarankin. In 2014, he and Zabarankin develop a theory for studying the risk of catastrophic events.

    In 2021, he publishes “Landscape of 21st Century Mathematics,” a book that presents recent results with context, background, and definitions for each theorem.

  7. 2024

    The FrontierMath benchmark

    In 2024, he co-authors FrontierMath, a benchmark of hundreds of original mathematics problems crafted and vetted by expert mathematicians to evaluate advanced mathematical reasoning in AI.

  8. As of October 2026

    Math problems for frontier models

    As of October 2026, he is an associate professor of mathematics at the University of Leicester and works with Surge AI to create and test mathematical problems that challenge current models.
