About me...

I do physics and programming. My research interests are nonlinear lattices, multi physics simulations, time series analysis, statistical physics, and computational physics. Recently, I have finished my PhD study about compaconts in strongly nonlinear lattices. I have studied physics and finished my study with a diploma thesis about nonparametric embedding, a time series analysis tool for reconstruction of dynamical systems.

I also run a personal webpage and ablog.

...and my Work

Time series analysis

  • Nonparametric regression and reconstruction of dynamical systems
  • Numerical differentiation of data
  • Modeling of dynamical systems, application to chemical oscillators, accoustical systems

Nonlinear lattices

  • Nonlinear oscillator lattices, Hamiltonian lattices
  • Traveling waves in lattices, i.e. Solitons and Compactons
  • Application of numerical methods to determine the shape of traveling waves
