Mirko Holler (Scientist) is responsible for instrumentation for high-resolution hard X-ray 3D microscopy and related experiments. Before joining PSI, Mirko Holler studied Physics at ETH Zurich and finished with a diploma degree in experimental physics in the group of Prof. Ursula Keller. He continued his work in Keller’s group developing a beamline for attosecond time resolved experiments. After finishing his PhD on “Attosecond strong field control” in 2010, he joined the Paul Scherrer Institute. Mirko's research focuses mainly on the methodological development of high-resolution 3D X-ray imaging, mainly on the instrumentation. The goals are to simplify the application of the techniques and to achieve faster measurement times, increase resolution and sample volume. This also involves aspects such as sample preparation and radiation damage. Mirko regularly applies such instruments in measurement campaigns, recently focused to the non-destructive imaging of integrated circuits and brain tissue.
