Curriculum Vitae

ALEXANDER NEUMANN was born in Hamburg, Germany, in 1984. He received his diploma in physics from the University of Hamburg, Germany, in 2010. From 2010 to 2014 he worked as a research assistant at the Institute of Applied Physics (University of Hamburg) in the group of Prof. H. P. Oepen. Within the group he studied the magnetic behavior of single ferromagnetic nanostructures.

Since the beginning of 2015 he is employed as a research scientist at the Institute of Medical Engineering at the Universität zu Lübeck.
