About
Fabian Lenzen is a postdoctoral researcher at Technische Universität Berlin in the Discrete Mathematics/Geometry group under Prof. Michael Joswig. Previously, he completed his PhD under Prof. Ulrich Bauer at TU Munich. His work bridges theoretical mathematics and computational applications.
- Research Focus: Algebraic topology, computational geometry, and their applications in data analysis
- Key Concepts: Topological data analysis, persistent homology, combinatorics, mathematical software development
His publications explore:
- Algebraic shifting techniques (2025, 2024)
- Two-parameter persistence algorithms (2023, 2024)
- Clifford-symmetric polynomials (2023)
- Categorical structures in representation theory (2021)
Software contributions include 2pac for two-parameter persistent cohomology and a TU Berlin Beamer theme aligning with university design standards. He actively develops LaTeX packages and visualization tools for mathematical education.
