Further Experiences
5/2013 – 3/2017
Student research assistant at the Goethe University Frankfurt in the field of electron probe microbeam analysis (EPMA), secondary electron microscopy (SEM) and X-ray fluorescence spectrometry (XFA). The tasks include measurements for industry and research, specimen preparation, standardisation, basic maintenance and computational analysis (including machine learning, statistics and regression models).
5/2015 – 8/2015
Visiting student researcher at the MIT - Woods Hole Oceanographic Institution (WHOI). The aim of the visit was to determine H/D fractionation between apatite and melt at different pressures and temperatures. Research included working with piston-cylinders, high-temperature furnaces, secondary ion mass spectrometry (SIMS) and analysis.
3/2013 – 5/2013
Intern at the European Space Agency (ESA), based at the European Space Research and Technology Centre (ESTEC) in Noordwijk, Netherlands. The aim of the internship was to assess the greenhouse effect on Mars using 3D global climate models (GCM) with implementations on Fortran- and MATLAB codes.
