Research Overview
Our group works on leveraging interfacial science and instabilities to enhance transport
in diverse technologically relevant areas. A prominent aspect of our research involves
developing reduced-order models for physico-chemical transport processes to gain analytical
or semi-analytical insights. Some of our recent efforts have been aimed at developing
fundamental understanding of wetting alteration using electric fields, investigating
the origin of self-assembled pattern formation in porous anodic oxides, non-linear dynamics
of liquid jet breakup, as well as development of theoretical models for active swimming droplets.
