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.
