Doctoral Theses at M15

Steffen Peter: Algorithms for Robust and Fast Sparse Recovery:
New Approaches Towards the Noise Folding Problem and the Big Data Challenge

"You are not expected to "finish" your Ph.D. at M15. You are expected to work as a young researcher, publish high quality work in renowned journals, and develop personally and individually. The academic title is consequently a byproduct. While outstanding work is demanded from you, Prof. Fornasier supports you with his profound technical knowledge, financial support for conferences, necessary devices, and contacts to the best researchers in the field. He accompanies your way to your own scientific profile as a mentor, not as a boss. With the right dose of personal and technical advice, he is able to push you to your limits.

In my Ph.D. at M15, I had the opportunity to work on algorithms for fast and robust sparse recovery, and evaluate them on the SuperMUC cluster Pfeil in cooperation with the German Aerospace Center (DLR). A research stay with Prof. Baraniuk at the RICE University, Houston, allowed me to get insight into a different (scientific) culture. I could achieve my personal scientific goals in a very friendly environment among the other young and dynamic team members of the chair."

Barcelona Graduate School of Economics


"As a Ph.D. student of M15, I worked on sparse optimal control problems related to multiagent systems: I had the chance to work on cutting edge mathematical issues, collaborate and network with top experts in the field, and present my work at several conferences around the world. I chose M15 to pursue my Ph.D. title because I was impressed by the international atmosphere that you can breathe inside the group, the great interaction between junior and senior collaborators, and the diversity of topics on which one can focus on.

Due to this broad spectrum of interests, M15 has been a fantastic school where I have learned the necessary tools to frame and tackle the mathematical challenges that can be found in both industry and academia. I'm currently concluding a Master of Finance at the Barcelona Graduate School of Economics and I will be taking part to an internship at the European Central Bank (ECB) in the next months."

Marco Artina: Lagrangian Methods for Constrained Non-Convex Minimizations
and Applications in Fracture Mechanics

"My doctoral studies at M15 have been realized within the Graduate Program of the IGDK 1754. The main focus of the work was to develop efficient numerical methods to solve linearly constrained non-convex and non-smooth minimization problems, with applications in fracture mechanics. In particular, I investigated two aspects: the development of an algorithm that allows for finding critical points of non-convex and non-smooth functionals subject to linear constraints and the introduction of anisotropic mesh adaptations for an efficient and correct detection of the crack path. The three years doctoral experience at M15 and IGDK 1754 has been for me very exciting as I had the occasion of working in a truly international environment.

Although I had a limited time to develop my doctoral work, I have been strongly supported by my supervisor Prof. Massimo Fornasier, allowing me to conclude my thesis with several publications. Working at M15 was real fun, facing interesting mathematical challenges of functional analysis and numerical analysis, developing algorithms that may find real-life applications, getting extremely stimulating inputs from the members of the Chair, and working in a friendly and dynamic environment.

I'm currently working as a Consultant at Strategy Engineers GmbH & Co. KG."
