I am a professor (W1) of Stochastic Analysis at the University of Greifswald.
Email: first name . last name at gmail . com
Currently, I am offering, together with Dr. Malter Gerhold, a Master thesis in random matrix theory and neural networks.
Moreover, if you are generally interested in doing a Master thesis in the area of algebra, machine learning or statistics, please send me an email!
Each Friday, at 14:30h, I co-organize an online seminar on Algebra, Combinatorics and Perspectives in Mathematical Sciences.
Each Wednesday, at 17:00h, I co-organize an online reading group on operads.
Please send me an email if you are interested in any of them.
