Fabian Reimers

Dr. Fabian Reimers is a Lecturer at the Department of Mathematics (M11) within the TUM School of Computation, Information and Technology (CIT) at the Technical University of Munich. His research focuses on algebraic structures, invariant theory, and group actions, with notable contributions to separating invariants and permutation group invariants. He co-authored the textbook Linear Algebra: With an Introduction to Discrete Mathematics and Set Theory (Springer, 2022), and maintains solution videos for its exercises on YouTube.

Reimers has taught extensively across undergraduate courses in linear algebra, discrete structures, and algebraic number theory. He has received multiple 'Golden Circle Teaching Awards' for his tutorials and lectures. His research includes presentations at conferences such as the SIAM Conference on Applied Algebraic Geometry (2019) and the Bilkent Algebra Seminar (2020).

Key research areas include vector invariants, modular invariants, and separating invariants over finite fields. His work often intersects with algorithmic algebra and computational aspects of group theory.
