Helmholtz-Zentrum Hereon

The Helmholtz-Zentrum Hereon conducts cutting-edge international research for a changing world: Around 1,100 employees contribute to the tackling of climate change, the sustainable use of the world's coastal systems and the resource-compatible enhancement of the quality of life. From fundamental research to practical applications, the interdisciplinary research spectrum covers a unique range.

Institute of Materials Physics

The Institute of Materials Physics operates instruments on large-scale equipment for structural investigations of materials and works on the development and characterization of novel light­weight materials for high-temperature applications, for example in aircraft turbines and automotive engines. Hereon has a unique infrastructure for complementary materials research with photons and neutrons.

Data scientist / research software developer for the multimodal and multiscale image analysis of X-ray tomography and transmission electron microscopy data

Reference code: 50066332_2 – 2021/WP 7
Commencement date: as soon as possible
The place of employment is Hamburg.
Application deadline: September 12th, 2021

Helmholtz-Zentrum Hereon is operating an outstation on the DESY campus in Hamburg. At the synchrotron radiation source PETRA III at DESY, our Institute of Materials Physics operates imaging beamlines for X-ray tomography (P05 IBL, P07 HEMS) along with supporting laboratory instrumentation (FIB-TEM, CT) for academic and industrial users. Our Institute of Metallic Biomaterials develops and studies biodegradable magnesium alloys as implant material. Using multimodal imaging, we aim to understand the mechanisms that control the interactions between the material microstructure and its mechanical, corrosive and biological properties. In order to enhance the material characterization, we aim to establish a platform for the analysis of multimodal and correlative data from micro- and nano-tomography as well as transmission electron microscopy. We are therefore looking for a data scientist or research software developer to analyze multimodal and multiscale image data. The acquired data will serve in material simulations and for the development of digital twins.

You will be responsible for developing vocabulary and schemes for describing correlative methods for material characterization using X-ray imaging and electron microscopy. You will develop analysis methods for data from experiments for the multiscale and multimodal in situ characterization using synchrotron radiation-based tomography and transmission electron microscopy. The algorithms to be considered include classical as well as machine learning methods of (image) data analysis. Additionally, you will be responsible for the seamless integration of measurement data and associated digital laboratory books into a metadata repository optimized for materials science applications. You will create generic workflows that represent and structure, facilitate the exchange of, and show the relationship between the acquired experimental (meta)data. The position is initially limited to 3 years.

The advancement of equality at the Helmholtz-Zentrum Hereon is a matter of course; in particular, we are striving to increase the percentage of women in the science sector.
