Hidden structures in Atom Probe Tomography data
Dr. Sebastian Koelling is working as a research associate at Polytechnique Montreal. He earned his PhD at IMEC in 2012 working on establishing Atom Probe Tomography as a viable analysis method in monitoring semiconductor manufacturing processes.

Advancements in the processing of aerospace alloys enabled by correlative microscopy
Sophie Primig is a Professor in the School of Materials Science & Engineering at UNSW Sydney. She was awarded both her MEng (2008) and PhD (2012) in Materials Science & Engineering from Montanuniversitaet Leoben, Austria. Following a short period as Post-Doctoral Researcher and an academic position at Leoben, she moved to UNSW Sydney in 2015, initially as Lecturer. She was an Australian Research Council (ARC) DECRA Fellow (2018-2020) and a UNSW Scientia Fellow (2019-2022).
Her research interests are in Physical Metallurgy. She has a track record in both fundamental and applied research. Her research goal is to develop an advanced capability in structure-property relationships across the processing routes of structural metallic materials via additive manufacturing and advanced thermo-mechanical routes. She combines state-of-the-art experimental techniques such as multiscale correlative microscopy including atom probe microscopy with mechanical testing and contemporary modelling approaches. The focus of her research is on aerospace alloys, and this has often been linked closely to the needs of industrial partners.
Sophie has attracted funding via the ARC Linkage and Discovery schemes, industry collaborations, and the Australia-US Multidisciplinary University Research Initiative Program. She is an Editor of Journal of Materials Science, Vice Chair of the TMS Phase Transformations Committee, and former President of the Materials Australia NSW Branch.

A fully open source toolchain for atom probe tomography of hydrogen
Peter Felfer is currenlty holding a professorship in atom probe tomography and 3D nanoanalytics at the Friedrich-Alexander Universität Erlangen-Nürnberg. He received his MSc. in Materials Science from the Leoben University in Austria and a PhD from the University of Sydney. His research focus for much of his career was the characterization of metallic materials, especially steels and superalloys. In recent years, after receiving an ERC starting grant for his project ‘Fundamentals of Hydrogen in Structural Materials’ he has been developing a research program in the area of structural materials for hydrogen applications. This includes experiments for materials characterization (APT, TDS) starting at very low hydrogen partial pressures of 10-12 mbar up to hydrogen exposure at high hydrogen pressures of 1000 bar, thus spanning 18 orders of magnitude. With his research group, he has built and developed custom made APT instrumentation including an ultra-low hydrogen APT instrument, cryo transfer equipment and a FIM. This was done together with software development for APT data acquisition, calibration/ reconstruction and 3D data analysis. All this forms an end-to-end APT toolchain that is fully open source for anyone to build their own system for custom experiments.
Ingrid McCarroll, PhD
Senior Research Associate

Re-evaluating our understanding of magnesium oxidation using atom probe tomography
Dr. Ingrid McCarroll has recently taken up a position as a postdoctoral researcher at the Max Planck Institute for Iron Research. Her previous experience includes 4.5 years as a senior research assistant at The University of Sydney, where she fulfilled the role of Atom Probe Scientist. Ingrid completed her PhD with Prof. Julie Cairney at The University of Sydney using atom probe tomography to study oxidation of steels and magnesium alloys. As part of her PhD, Ingrid spent a year at The University of Oxford where she developed, in collaboration with Dr. Daniel Haley, a reaction cell attached to an atom probe. This reaction cell enabled the deuteration and oxidation of materials, with direct vacuum transfer between the reaction cell and the atom probe analysis chamber. In her role as atom probe scientist, Ingrid continued to develop methodologies for studying early oxidation of magnesium alloys and the deuteration of materials. Together with Alexander Rosenthal she implemented equipment that enabled a cryogenic and vacuum transfer integrated laboratory, connecting a FIB/SEM, atom probe, and purpose-built glovebox. Ingrid’s studies include the relationship between hydrogen and the embrittlement of steels and the influence of hydrogen on the early stages of magnesium corrosion.
