We measure the basic forces that operate between molecules that are manifest at interfaces. These forces control the stability of colloidal systems from blood to toothpaste. We use very sensitive techniques that are able to measure tiny forces with sub nanometer distance resolution. Understanding these forces enables us to predict how a huge variety of colloidal systems will behave.

We are seeking students to perform fundamental research into how different ions exert influence in a myriad of systems.

Nanobubbles are simply nanosized bubbles. What makes them interesting? Theory tells us they should dissolve in less than a second but they are in some cases stable for days.

We are studying colloidal systems in highly concentrated salt solutions. Here a number of surprising and unexplained things happen that are associated with surprisingly long-ranged electrostatic forces
