I’m a post-doctoral researcher working on the project on frequency combs of the CRC “Wave phenomena: analysis and numerics”. In October 2025, I defender my PhD under the supervision of Prof. Wolfgang Reichel.

Research interests

• Nonlinear partial differential equations
• Existence and stability of nonlinear waves
• Bifurcation theory
• Numerical continuation and bifurcation
• Nonlinear optics
