Andrea Kirsch
ORCID: 0000-0003-2602-7415
Andrea did her PhD at the University of Bremen, Germany, where she worked on the synthesis, structure, and properties of bismuth iron oxides. After graduating in 2018, she held a postdoctoral fellowship from the German Research Foundation to work with our group. She joined in November 2019 and uses neutron and X-ray scattering techniques with subsequent Rietveld and PDF analysis for formation studies of complex oxides, e.g., high-entropy and quantum materials.

Adam received his MChem degree in Chemistry in 2018 from the University of Oxford. He then completed his PhD at the University of Cambridge. His PhD focused on the atomic structure, physical properties and formation mechanisms of amorphous metal–organic frameworks and involved using several scattering, spectroscopy and microscopy techniques. In December 2022, Adam joined our group and will investigate the formation of metal oxide clusters in solution.

Rebecca Pittkowski
ORCID: 0000-0002-0351-4993
Rebecca is a postdoc who joined our group in August 2021. Rebecca finished her PhD in December 2020 at the J. Heyrovský Institute in Prague, where she worked on the development and testing of novel oxygen-evolving electrocatalysts. After graduation, she joined CHEAC and the group of Matthias Arenz in Bern for a 6-month stay before moving to Copenhagen. Here, she works on the synthesis of high entropy alloy nanoparticle electrocatalysts and their structural characterization through X-ray scattering and X-ray absorption methods. Rebecca also applies these techniques in operando studies, which allow her to follow structural changes of nanoparticles during electrocatalysis.

Adrián Sanz Arjona
ORCID: 0000-0003-3208-5929
Adrián joined our group as a postdoc in May 2022 after completing his PhD at Trinity College Dublin, Ireland. During his PhD under the supervision of Prof. Peter Dunne, his research was focused on the hydrothermal synthesis of various minerals and the structural characterisation for controlling material characteristics under various synthetic conditions. Once he joined our group, he started investigating the synthesis and characterisation of amorphous oxides for applications in several fields, such as electrocatalysis. His project requires, among others, the use of X-ray diffraction methods, PDF analysis and spectroscopic characterisation of the targeted materials.

Andy started his MSc+PhD program in our group in September 2018 but has already been working with our group since his undergraduate studies. Initially, he applied combined PDF and SAXS modelling to understand how metal oxido clusters form in solution. In recent years, however, his scientific interests shifted towards machine learning based modelling of scattering data.

Laura studied chemistry at Ludwig Maximilian University of Munich and the University of Helsinki, focussing on inorganic and theoretical materials chemistry. She moved to Copenhagen to conduct her MSc project in our group and subsequently started her PhD studies in February 2022. Laura investigates the solvothermal formation of ternary oxide materials with special emphasis on when and how the mixing of metals takes place.

Emil Thyge Skaaning Kjaer
ORCID: 0000-0002-0298-6016
Emil started his PhD in September 2019 but had been working with the group as part of both his BSc and MSc project. Emil works on automating data treatment and especially PDF modelling for in situ studies.

Jens Edelvang-Pejrup
ORCID: 0000-0002-2385-0396
Jens did his BSc project in our group investigating the relationship between synthesis and structure of layered double hydroxides. He has been enrolled in the integrated MSc+PhD program since February 2022 and works on the development of novel high entropy oxides based on earth-abundant elements. His focus lies on their application as catalysts for the oxygen evolution reaction. By combining several experimental approaches, he aims to relate the electrochemical properties of these materials to their atomic scale structure.

Tobias Mølgaard Nielsen
ORCID: 0000-0002-5976-9928
Tobias joined our group during his undergraduate studies and conducted a project on the synthesis of manganese dioxide polymorphs.
