Martin Aeschlimann (born 1957) is a Swiss physicist and professor in the physics department of the University of Kaiserslautern.

The following year Aeschlimann became a research associate at the NSF-Center for Photoinduced Charge Transfer at the University of Rochester.

In November 1996 he habilitated with his thesis: "Time Resolved Studies of Electron Relaxation at Metal Surfaces" [3] followed by his promotion to professor of experimental physics at the University of Duisburg-Essen.

For the experimental approach, novel methods are constantly developed for measuring ultrafast relaxation processes in real time with high temporal and spatial resolution.

This is in general achieved by combining ultrashort pulsed laser systems with surface science technology, nano optics and magnetism.
