Research Interests

Fluid Dynamics.
Drag reduction and energy saving by introducing a lubricating gas layers on solids moving in liquid: plastron on superhydrophobic surfaces, Leidenfrost vapor layers and streamlined gas cavities attached to a falling sphere. Effect of the fluid interface mobility on the interaction between bubbles and droplets.

Colloid and surface science.
Force measurement on micro and nanoscale using the atomic force microscopy (AFM) colloidal probe technique: microparticles adhesion, nanoscale friction and wear in solutions. Soft matter interactions: AFM colloidal probe measurement of forces between droplets, bubbles and living cells. 
Effect of the wettability and surface roughness on the heat transfer and boiling regimens on heated solid in contact with water. Nanoparticles selfassembly into functional microwire networks by evaporative lithography.
