Summary of Expertise

My scientific expertise is in characterizing magnetic materials with polarized x-rays. I am primarily using x-ray spectromicroscopies, which allow me in a unique way to image with almost nanometer spatial and better than 100 ps temporal resolution spin textures and their fast dynamics with elemental and magnetic sensitivity. I am also strongly engaged in developing novel  x-ray instrumentation such as magnetic x-ray tomography.

Research Interests

• magnetism on the nano- and mesoscale
• magnetic x-ray microscopy and spectroscopy
• (ultra-)fast spin dynamics
• soft x-ray tomography of condensed matter
• x-ray optics

Biography, Education and Training

I studied physics at the TU Munich/Germany and received my Dr.rer.nat (PhD) for my thesis “X-ray magnetic circular dichroism at the L2,3 edges of 4f-elements” in 1993. In 2000 I received my habilitiation (venia legendi) from the U Wuerzburg in Germany based on my pioneering work on magnetic soft X-ray microscopy. From 2001-2004 I was group leader at the Max-Planck-Institute for Metals Research in Stuttgart/Germany and lecturer for experimental physics at the U Stuttgart/Germany. In 2004 I joined the Materials Sciences Division at Lawrence Berkeley Laboratory as Staff Scientist and Principal Investigator. I was promoted to Senior Staff Scientist in 2016. In 2014 I was appointed as Adjunct Professor in Physics at UC Santa Cruz. Since 2015 I have been serving  the Materials Sciences Division at Berkeley Lab as Deputy Division Director, being Interim Division Director from 2016-2017.
