The research is focused on qualitative and numerical aspects in the field of the dynamics modeling of curvature driven flows of plane closed curves. We also focus on the study of various nonlocal geometric flows preserving geometric quantities, such as area or length. Special attention is paid to the design of numerical schemes that are optimal in terms of discretization points distribution on evolving varieties. Finally, we study applications in the field of phase interface dynamics and dislocation loops in materials research.
