Research Interests:

Currently my research focuses on the temperature dependence of nanoscale friction. I use AFM probe tips with an integrated solid-state heater which enables heating the tip up to 800°C within milliseconds. With these probes I investigate single asperity silicon-silicon contacts in controlled atmosphere.

In general, I am interested in surface science and in lessons we can learn from biological systems.
