Biography

I studied Physics with focus on Medical Physics at the FAU Erlangen-Nürnberg and obtained the diploma degree in 2010. I finished my diploma thesis “Optimization of Reconstruction Algorithms in Electron Tomography” at the Institute of Medical Physics (IMP) of the FAU (supervisor: Prof. Dr. Marc Kachelrieß). During my Erasmus studies at the University of Cantabria in Santander (Spain) I obtained a diploma degree in “European Business and Economics” in 2007.

In 2016, I received a doctoral degree in engineering (Dr.-Ing.) with the corresponding PhD thesis titled “Quantitative Electron Tomography of Functional Nanomaterials” realized at the IMN and CENEM of the FAU Erlangen-Nürnberg (supervisor: Prof. Dr. Erdmann Spiecker). In 2013, I was a visiting PhD student at the University of Cambridge (UK) in the Electron Microscopy Group (Prof. Dr. Paul Midgley) for a project within the European Network for Electron Microscopy (ESTEEM2). Since 2018, I am Academic Advisor (German Akademischer Rat) at IMN and CENEM.

My research interests include:
+ nanotomography (electron tomography, Nano-CT, FIB-SEM slice & view tomography) of porous and nanoparticulate materials (amongst others)
+ conventional, 360° (“on-axis”) and cryo electron tomography
+ correlative and scale-bridging tomography approaches
+ segmentation and quantitative analyses of tomographic datasets
+ time-resolved nanotomography of in situ experiments, e.g., nanomechanics or heating experiments
+ optimization of 3D reconstruction techniques
+ development of optimized preparation techniques for electron tomography
+ application of conventional and analytical TEM techniques

My tasks comprise amongst others:
+ contact person for scientific collaboration requests and industry projects using CENEM’s electron microscopy facilities
+ contact person for requests for training within the CENEM user facility
+ facility co-supervisor of the double Cs-corrected, monochromated FEI Titan Themis 300 TEM
+ contact person for IZNF-related issues (deputy property manager)

Furthermore, I partly hold teaching obligation for the following lectures and practical courses:
+ “Transmissionselektronenmikroskopie in Materialforschung und Nanotechnologie 2” (Master’s degree course; summer semesters)
+ “Grundlagen der Nanotechnologie – Charakterisierung” (Bachelor’s degree course; summer semesters)
+ “Praktikum Nanotechnologie Synthese/Charakterisierung von Nanopartikel” (Master’s degree course; winter semesters)
