I am currently supervising Bachelor and Master Theses in the area of stochastics at the University of Innsbruck. A (not updated) list with possible topics can be found here Topics for master theses. If you have any other suggestions, I would be happy to accomodate you, if this fits in my area of expertise. Just come for a chat (virtual one) and we can find something suitable, depending on your mathematical interests.
If you have good programming skills, there are several topics available that involve simulations (Python, R, or whatever you want) of random processes.

General information and requirements: The courses Stochastics 1 and Stochastics 2 are needed (=passed) for the topics that involve stochastic processes. The thesis can be written in English or German. A list with available/potential topics can be found here Topics for bachelor thesis.
