Jonas Stelzig

Dr. Jonas Stelzig is a Senior Lecturer in the School of Mathematics at Ludwig Maximilian University of Munich (LMU). He is currently on leave during the summer term 25 to substitute a position at Johannes Gutenberg University Mainz, where he teaches Riemann surfaces and a seminar on topological K-theory. In 2026, he will assume a Heisenberg-position funded by the German Research Foundation (DFG).

• Current Role: Senior Lecturer (Privatdozent) at LMU
• Leave Status: Substituting a position at Mainz (2024)
• Future Role: DFG Heisenberg-position (2026)

Stelzig's research lies at the intersection of Geometry, Topology, and Number Theory. He specializes in (almost-)complex manifolds, particularly their cohomology and rational homotopy theory. His work explores the interplay between algebraic structures and geometric properties, such as Massey products, formality, and bigraded cohomological notions.

Recent publications focus on cohomological properties of Kähler and non-Kähler manifolds, rational homotopy theory, and spectral sequences. He collaborates with researchers like G. Placini, L. Zoller, and A. Milivojevic, contributing to journals like Advances in Mathematics and Mathematical Research Letters.

Teaching highlights include courses on complex geometry, topology, and homotopy theory. He co-organizes workshops like Geometry and TACoS and participates in international conferences, including Luminy (2024), Osaka (2022), and Banff (2019).
