Johannes Walcher

As a Mathematical Physicist, I am interested in understanding both how the world works, and what this means in abstract terms. I am currently Professor at Heidelberg University, work at the Institute for Mathematics, teach at the Faculty of Mathematics and Computer Science, and also supervise students from the Department of Physics and Astronomy.

Current Teaching
In the Winter Semester 2025/26 I am teaching the beginner level class Höhere Mathematik 1
for physics students. With Ondra Hulik, we are offering a seminar on advanced String Theory. The Rhind Seminar continues as before.
