Olivier Sète

Olivier Sète is a postdoctoral researcher in mathematics at Universität Ulm. His work focuses on numerical mathematics, computational complex analysis, and their applications in mathematics and sciences. He has held teaching roles at institutions including TU Berlin and Universität Greifswald, covering courses such as Numerical Linear Algebra, Analysis, and Partial Differential Equations. His research interests include approximation theory, numerical methods for the Helmholtz equation, conformal mapping, potential theory, and harmonic mappings in astrophysics.

Notable contributions include the AAA algorithm for rational approximation, which earned the Frontiers of Science Award in 2023. His research spans topics like lemniscatic domains, polynomial pre-images, and stochastic Galerkin methods. He has developed software tools like the Transport of Images Toolbox for computing zeros of harmonic mappings. His work bridges theoretical mathematics with computational applications, addressing challenges in complex analysis and numerical methods.

Awards include the Frontiers of Science Award for his work on the AAA algorithm. He has collaborated extensively with researchers such as Yuji Nakatsukasa and Lloyd N. Trefethen. His academic background includes a PhD from TU Berlin (2016) and a Diplom from TU Berlin (2009).
