Brynjulf Owren

Brynjulf Owren is a Professor at the Department of Mathematical Sciences, Norwegian University of Science and Technology (NTNU), since January 1994. He holds a Doktoringeniør (PhD) in Numerical Analysis from NTH (now NTNU) and has extensive research experience in numerical analysis, differential equations, and geometric integration. His work includes leading projects like GALA (EU Sixth Framework Programme) and SPIRIT (Research Council of Norway) and serving as Vice Dean of Education at NTNU's Faculty of Information Technology and Electrical Engineering (2012–2017).

Education: PhD in Numerical Analysis (1990, NTNU), MSc in Physics and Mathematics (1984, NTNU). Research focuses on numerical methods for differential equations, geometric integration, and mathematical modeling. He has supervised 10 PhD and 31 MSc students. Leadership roles include President of the Norwegian Mathematical Society (2007–2011) and membership in SEFI and ECMI.

Research interests span geometric numerical integration, structure-preserving methods, and applications in computational physics and machine learning. His work bridges theoretical mathematics and computational science, emphasizing methods that preserve geometric properties of dynamical systems.

Key contributions include advancements in Lie group integrators, Kahan discretization, and energy-preserving algorithms. Collaborations with institutions like SINTEF and international projects highlight his interdisciplinary impact. Current projects explore neural networks’ integration with differential equations and scientific computing.
