Student Area


This is the right page if you are looking for a bachelor's project.
And it is also the right page if you are looking for a master's project.

Office hours concerning my courses are before/after the course, or by arrangement.
Sprechstunde bez. Lehrveranstaltungen ist vor/nach der Lehrveranstaltung, bzw. nach Vereinbarung.

Erasmus: I am coordinator for mathematics. If you want to do an Erasmussemester, have a look here and contact me as soon as possible for a chat. If you are an incoming student and run into problems, don't hesitate to contact me for all sorts of trouble shooting.

Bachelor's projects

In case of interest in one of the proposed projects, contact me before the beginning of the 'Seminar with Bachelorarbeit'.
If the project you are interested in is not mentioned below but should be, come for a chat way before the beginning of the 'Seminar with Bachelorarbeit'.

Master's projects

I offer master's projects in the areas of signal processing, sparse approximation, dictionary learning and machine learning.
Recommended prerequisites are good knowledge of linear algebra and probability theory and/or functional analysis.

The goal is to contribute to an active area of research and so the project will be tailored to currently open questions and your personal interests.

In case of interest have a look at the research or publications page and contact me for a first chat.
