Uli Walther works in commutative algebra and algebraic geometry, focusing on tools like local cohomology, singularities of polynomials, and systems of differential equations (called GKZ or tautological systems) that arise from geometric configurations. Much of this research connects abstract algebraic structures to combinatorial objects such as matroids and graphs, including applications to Feynman diagrams from physics. Prospective students would be working on theoretical mathematics that bridges algebra, geometry, topology, and combinatorics.
Publication output has been fairly steady over the past decade, with a notable peak in 2021 and a slight dip afterward before rising again in 2025-2026.
