Ivan Tomasic

Ivan Tomasic is a Reader in Pure Mathematics at the School of Mathematical Sciences, Queen Mary University of London, where he has been a faculty member since 2007. He is affiliated with the Centre for Combinatorics, Algebra and Number Theory, contributing to research in logic and algebraic geometry.

His research lies at the intersection of mathematical logic and algebraic geometry, particularly in model theory, categorical logic, topos theory, difference algebra, and differential algebra. Tomasic's long-term programme focuses on developing Relative Algebraic Geometry over a base topos, with applications in dynamics and algebraic structures. His work bridges deep logical frameworks with geometric intuition, advancing foundational theories in difference and differential algebra.

His recent publications show a strong trend toward categorical and topos-theoretic methods, especially in generalizing classical algebraic geometry to difference fields. Key themes include Galois stratification, cohomology, definable sets over finite fields, and zeta functions, reflecting a unified vision of logic, geometry, and arithmetic.

Tomasic has secured multiple research grants from the EPSRC, including projects on stability in model theory and category theory, cohomology of theories, and model-theoretic views of difference algebra. These grants support his ongoing collaborations, such as with Behrang Noohi, and sustain his research programme.

He is involved in a vibrant research environment at Queen Mary, particularly within the Centre for Combinatorics, Algebra and Number Theory, where he contributes to seminars, collaborative research, and mentoring of early-career researchers.
