Area of Interest: 
Thin films, Adhesion-debonding of Soft Interfaces, Microfluidics, Complex fluids, Electrokinetics, Li-ion batteries, Supercapacitors, Electrolytes.

I am interested in the theories and experiments interconnected to a wide spectrum of multi-scale problems in fluid mechanics, transport processes, interfacial science, hydrodynamics, and electrochemical storage devices (such as next-gen batteries). Frequently use continuum-scale modelling, linear stability analysis (LSA), nonlinear simulations, advanced imaging techniques (such as Optical Microscopes, AFM, SEM, TEM, etc.), and sophisticated characterization to analyze and investigate the problem of interest. I am quite open and feel encouraged to resolve any unsolved problems that I come across using my expertise and understanding.
