Our research is centered around the dynamics of non-equilibrium systems. We explore their behavior experimentally and theoretically. Our experimental studies focus on the reaction dynamics of electrochemical systems, such as the CO2 reduction and the hydrogen evolution reaction. Our prototypical experimental model system for the study of pattern formation and emergent behavior is the electrodissolution of Si. Our theoretical questions deal with universal behavior in certain classes of non-equilibrium systems. Most of these studies are motivated by our experimental results, but address fundamental laws that govern behavior in complex systems. Examples include collective dynamics of coupled oscillators and pattern formation in reaction-diffusion systems.
