Jean Paul Schemeil

I am a Ph.D. student in mathematics at the University of Nottingham, supervised by Prof. Alexander Vishik.

Research

Broadly speaking, I am interested in the study of algebraic invariants in geometry and topology. My current research focuses on motivic tensor-triangular geometry.
