Overview

My research focuses on leveraging interfacial instabilities to enhance transport in microfluidic and microgravity settings. A prominent aspect of my research involves developing reduced-order models for physico-chemical transport phenomena. Specific areas of interest include stability theory, nonlinear dynamics and pattern formation in multiphase systems.
