I am a postdoc researcher with research ambitions at the at the intersection of mean-field particle models, control theory and mathematics of machine learning. I am at the Chair for Dynamics, Control
and Numerics headed by Enrique Zuazua. Before, I was a postdoc at TU Vienna at the Institute of Analysis and Scientific Computing in the group of Anton Arnold, where I also finished my PhD in 2020. In 2019, I was an invited guest of Prof. Shi Jin at Shanghai Jiao Tong University.

Large-time behaviour of mean-field equations
During my PhD, I focused on obtaining explicit and for application meaningful large-time estimates for mean-field equations by means of spectral theory and entropy methods. I am currently interested in including long-range particle interactions on large networks, which have many fascinating real-world applications, such as synchronisation and opinion formations.

Mathematics of machine learning
The achievements of machine learning algorithms are beyond impressive, but still surprisingly little is understood about why they work so well. The mathematician’s job is now to look behind the curtain and extend the vocabulary to describe what at this point seems like magic. I am currently investigating supervised learning procedures of neural networks and their lack of robustness from an optimal control perspective.
