Björn Liljegren-SailerView profile
Researcher
Björn Liljegren-Sailer is a Research Scientist at the Johann Radon Institute for Computational and Applied Mathematics (RICAM), part of the Austrian Academy of Sciences (OEAW), and an employee at MathConsult. His research focuses on computational methods for partial differential equations (PDEs), model order reduction, and port-Hamiltonian systems, with applications to gas networks, numerical analysis, and optimization. He holds a PhD in Mathematics from the University of Trier (2020) and a Master of Science in Technomathematics from Friedrich-Alexander-Universität Erlangen-Nürnberg (2015). Dr. Liljegren-Sailer’s work emphasizes structure-preserving numerical methods and system-theoretic approaches. Key contributions include error estimation for model reduction under inhomogeneous conditions, port-Hamiltonian approximations for nonlinear flow problems, and stability-preserving gas transport models. His research bridges theoretical advancements with practical applications in engineering and computational science. Publications span topics like damped wave equations on networks, input-tailored model reduction for quadratic-bilinear systems, and certified reduced basis methods. His work aligns with RICAM’s mission in mathematical data science and optimization, contributing to industrial collaborations through MathConsult. Though no formal awards are listed, his prolific publication record reflects recognition in computational mathematics and applied sciences. He advises no students currently listed but collaborates extensively on interdisciplinary projects.
