I’m Florian Schäfer, assistant professor in the School of Computational Science and Engineering at Georgia Tech.
Prior to joining Georgia Tech, I received my PhD in applied and computational mathematics at Caltech, working with Houman Owhadi. Before that, I received my Bachelor’s and Master’s degrees in Mathematics at the University of Bonn.
My research interests lie at the interface of numerical computation, statistical inference, and competitive games. To learn more, have a look at these high-level summaries or the defense of my thesis.
I am currently hiring PhD students. If you have a strong background in computational mathematics and the above seems interesting (or you have a project in mind that I might find interesting), feel free to reach out!

Jul 18, 2024 | I attended SciCADE 2024 and gave a talk on information geometric regularization in the minisymposium on Discretization Methods Involving Multiple Levels and Scales. |
Jul 12, 2024 | I gave a talk at the Fourth Symposium on Machine Learning and Dynamical Systems at the Fields institute. |
Jun 19, 2024 | Joint work with Jiong Chen and Mathieu Desbrun was selected for one of five best technical paper awards at SIGGRAPH ‘24! We use KL-optimal Cholesky factorization as a preconditioner to greatly accelerate the method of fundamental solutions. |
May 10, 2024 | Joint work with Yifan Chen and Houman Owhadi accepted at Mathematics of Computation. We use Cholesky by KL minimization to implement the GP approach to solving nonlinear PDEs at near-linear computational cost! |
