Björn de Rijk

Björn de Rijk is a Junior Research Group Leader at the Karlsruhe Institute of Technology (KIT), affiliated with the Institute for Analysis within the Department of Mathematics. He leads the research group 'Stability of Nonlinear Waves' and serves as a principal investigator in the Collaborative Research Center (CRC) 'Wave Phenomena'. His editorial responsibilities include membership on the board of Nonlinearity, and he is part of the KIT Young Investigator Network and KIT Center MathSEE.

Dr. de Rijk holds a PhD in Mathematics from Leiden University (2016), an MSc in Mathematics from Leiden (2012), and a BSc in Mathematics from Leiden (2010). He previously held positions as Acting Professor at Technical University of Munich (2020) and Postdoctoral Researcher at University of Stuttgart (2017-2021).

His research focuses on nonlinear PDEs, stability analysis, pattern formation, traveling waves, and reaction-diffusion systems. Key themes include spectral analysis of wave solutions, multi-scale dynamics in dissipative systems, and modulational instabilities in optical and fluid systems. His work bridges mathematical theory with applications in optics, fluid mechanics, and biological modeling.

Recent publications (2022-2025) demonstrate a consistent focus on wave stability in nonlinear systems, with advancements in understanding periodic wave trains, soliton dynamics, and shock extinction mechanisms. Common themes include rigorous analysis of spectral stability, asymptotic behavior of perturbations, and bifurcations in spatially extended systems.
