## General Teaching

I have made a Gaussian Elimination Calculator (or see Gauss-Jordan Algorithmus Rechner auf Deutsch) and an Inverse Algorithm Calculator (using Numbas), where you can enter a linear system as an augmented matrix, resp. a square matrix, and then tell it which row operations you would like to do. The aim is to enable students to concentrate on which steps are required to get the matrix into reduced row echelon form, rather than the individual calculations per entry.

## Current Teaching

In the winter semester 2023/24, I am assisting the course Linear Algbra for Physicists, lectured by Dr. habil. Vadim Alekseev, and holding exercise classes for the course Foundations of Mathematics, lectured by Dr. Norbert Koksch. I'm also teaching a maths outreach class on Thursdays for school years 10-11.

## Previous teaching

Summer 2022: Linear Algebra 2 for Bachelor, Linear Algebra and Analytical Geometry and maths outreach class

Winter 2022/23: Linear Algebra 1 and Linear Algebra for computer scientists

Summer 2022: Linear Algebra and Analytical Geometry and Mathematical Methods for computer scientists

Winter 2021/22: Linear Algebra for Physicists und Linear Algebra for computer scientists

In Leicester I taught Elements of Number Theory, Linear Algebra and Plane Geometry.

Lecture notes Linear Algebra

Workbook Linear Algebra

I also prepared some documents to help students transition to university mathematics. For example this Introduction to proofs.

### Cambridge Maths Tripos Groups Ia lecture course

In Michaelmas 2016 I lectured the Cambridge first year course on Groups (for the third time). Here is the lecture-accompanying blog Think for yourself, on which I particularly wrote about how to think about and learn maths at university.
