Droplet Oscillations
My research on droplet dynamics focuses on non-linear shape oscillations of inviscid liquid droplets, including axisymmetric and non-axisymmetric modes and their non-linear mode coupling. I develop and apply high-fidelity numerical methods to capture large-amplitude deformations and modal interactions. These studies provide insight into excitation mechanisms, energy transfer between modes, and the role of discrete symmetries.
