We launched the Surface-Topography Challenge, an international cooperative effort to improve the way we measure surface roughness.

The roughness of a surface controls the performance of everyday objects; like how well a tire grips the road, how your body responds to an implant, or how easily paint chips off a car door. Yet manufacturers and researchers lack are still looking for better ways to measure and describe roughness in order improve this performance.

Together with Prof. Lars Pastewka (U. Freiberg) and Prof. Martin Muser (Saarland U.), our group has launched the Surface-Topography Challenge. The purpose is to work together to advance our understanding in this area. We’re excited that research groups from around the world are participating.
