Prof Roger Horn

Research interests:

Roger Horn's research interests centre on interfaces, particularly interfaces between liquids and other materials. The properties of interfaces play a major role in how materials interact with each other through physical forces, and these interactions determine important phenomena including adhesion, lubrication, friction, colloidal stability, nanoparticle stability, static electrical charging, bioadhesion and wetting. Roger's particular expertise is in experimental measurements of forces between surfaces, and he has an international reputation for his innovative experiments in this area. His 72 journal articles have been cited over 5300 times. Roger currently holds two ARC Discovery grants to investigate interactions between bubbles in water.

Current projects:

• Bubble and drop collisions


• Origins of static electricity


• Optical interferometric methods for biosensing


• Electrostatic and electrokinetic properties of air-water interfaces
