Water droplets on a wettability gradient

Changes in hydrophobility are reflected in the changing contact angle along the gradient

Mica surfaces with local contamination

Newton’s rings are revealed between two mica sheets trapping a dust particle, in a Surface Forces Apparatus

Roughness influences contact angle

A microfabricated pillar-to-hole gradient is used to explore the influence of morphology on wetting

Laboratory for Surface Science and Technology

Our group has focussed on the application of surface-analytical techniques and functionalization approaches to problems of technological interest, particularly in the areas of tribology and biointerfaces.
