Dr. Sebastian Riedel

Welcome to my homepage! I am PostDoc at TU-Berlin, working in the group of Prof. Dr. Michael Scheutzow. I am also a member of the DFG funded research unit Rough paths, stochastic partial differential equations and related topics. You can find my professional CV here.

Please note: In winter term 2016/2017, I am a visiting professor at Universität zu Köln. My address here is:

For students: Bachelor's and Master's Theses

I am happy to supervise Bachelor's and Master's theses in probability theory and related fields. There are many possible topics I can offer to you, but your own proposals are also most welcome. In case you are interested, please send me an Email. In the following table you find the current and finished bachelor's and master's theses.
