Dipl.-Min., Dr. rer. nat., Clausthal University of Technology, Germany

Scientific Officer in Charge, Electron Microscopy and X-ray Microanalysis

General Responsibilities

Karsten joined the CSL in mid 2006 and is responsible for the Electron Microscopy and X-ray Microanalysis Facility, housing a Cameca SX100 electron microprobe, a FEI Quanta 600 ESEM, a Horiba XGT-7000V MicroXRF, light microscopy and sputter and carbon coaters. The facility serves university and external users from the earth sciences, chemistry, plant science, agricultural science, zoology, marine sciences and others.

Karsten is the Tasmanian representative of the The Australian Microscopy and Microanalysis Society (AMMS)

Career Summary

Karsten studied mineralogy in Hannover and Clausthal in Germany focussing predominantly on analytical geochemistry and applied mineralogy. He obtained his Dipl.Min. (Masters) in 1996 with a thesis on the analysis of sewage sludge ashes (to be used as an additive in brick making) and his Dr. rer. nat. (PhD) in 2000 with an EPMA-focussed work on the trace element distribution in basalt dikes intruded into evaporite domes (as a natural analogon to radioactive waste deposits). During his PhD he also operated the Cameca SX100 microprobe of Clausthal Uni. Afterwards he worked several years as a PostDoc in the field of materials science investigating ionic transport in semiconducting oxides by means of high temperature experiments and SIMS and EPMA analyses.
