Research

Research in my ‘Wave Lab’ explores on the interdisciplinary field of macroscopic spatio-temporal pattern formation and nonlinear phenomena.

We are investigating the propagation dynamics of excitation pulses in one-dimensional and linear and spiral-like excitation fronts in two-dimensional reaction-diffusion (RD) systems. Those systems can be planar or curved, and homogeneously or non-homogeneously. Currently, we are using chemical Belousov–Zhabotinsky reactions and combustible liquids to create RD pulses and waves.

We also started ‘rediscovering’ the Trevelyan rocker, a thermoacoustical, physical oscillator with research publications only between 1806 and 1923.

I am also working on various History of Sciences projects (e.g., CoW physics department and Arthur Compton, Boris Belousov and Anatol Zhabotinsky, Trevelyan rocker).
