The research in this group addresses fundamentals of the transport processes at the microscale across diverse domains such as interfacial heat and mass transfer in ultrathin films, digital microfluidics involving precise movement of droplets using Electrowetting on Dielectric (EWOD), magnetic field and surfaces with chemical gradients, design and development of micro-scale heat spreaders for cooling of electronic components, formation and propagation of cracks during drying of microdroplets, self-assembly of biomolecules and biological processes in small confinements, study of protein nanoparticle interaction, preparation of biomimetic surfaces, pattern recognition during blood droplet drying for diagnostics etc. Significant collaborations, both national and international, exist with other leading groups in these areas.
