My expertise and research interest lie in the field of fluid mechanics. The common theme of my research is the dynamics of liquid-gas interface or free surface ranging from micrometer to planetary length scale. The dynamics of free surfaces is particularly interesting to me as it is crucial in the transportation of various physical quantities. 

In smaller length scales, where surface tension is dominant, interfaces generate shapes countering gravitational pull in static equilibrium. When this balance is disturbed, they undergo complex yet fascinating shape transitions that involve surface tension, inertia, viscosity and sometimes even gravity until another equilibrium state is reached. These shape changes are strongly unsteady motions, extremely fast in some problems and often encounter singularities in their physical model.
