Leon Bungert is a postdoc at the University of Bonn, in the group of Franca Hoffmann. In 2020 he earned his PhD at the University of Erlangen under supervision of Martin Burger. His thesis “Nonlinear Spectral Analysis with Variational Methods” was awarded the Biennial French-German Mathematics in Imaging PhD Prize. Leon’s research focusses on variational methods with applications in data science, machine learning, and imaging. This includes PDEs on graphs, regularized training methods for neural networks, and nonlinear eigenvalue problems.
