Kirsten Marie Ørnsbjerg Jensen

Kirsten is an associate professor at University of Copenhagen, where she started our group in October 2015. She did her undergraduate and PhD studies at Aarhus University, where she worked in Bo B. Iversen’s group in the Center for Materials Crystallography. Following her PhD, Kirsten did postdoctoral work at Columbia University in New York in Simon J. L. Billinge’s group, using total scattering and PDF to study the structure of nanomaterials. Kirsten is leading the Nanostructure group at University of Copenhagen, focusing on mapping the relation between nanomaterial synthesis, structure and properties.

Rebecca Pittkowski
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.

Andrea Kirsch
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.

PhD students:

Andy Sode Anker
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.

Olivia Aalling-Frederiksen
Olivia is on the integrated MSc+PhD program, which she started in September 2019. Her research focusses on the synthesis and structural characterization of disordered oxide materials, including niobium oxides, as well as nickel/cobalt/iron oxides for catalysis.

Laura Susanne Junkers
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
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.

Baiyu Wang
Baiyu did her BSc studies at Wuhan Institute of Technology in China and her MSc at the University of Copenhagen. Her MSc thesis on molecular electronics was done with Kasper Nørgaard’s group next door, but since November 2019 she has been a PhD student in our group. Baiyu works on the synthesis and structural characterization of intermetallic nanoparticles.

Nicolas Magnard
Nicolas’ background is in materials science and engineering. He did his joint engineering and master’s degree at Université de Limoges, France, and has done research projects at both Université de Limoges and Uppsala University. Nicolas works on understanding material formation by studying polymorphism in oxide materials.

Tobias Mølgaard Nielsen
Tobias joined our group during his undergraduate studies and conducted a project on the synthesis of manganese dioxide polymorphs. For his BSc project he investigated the effect of synthesis parameters on the synthesis of spinel-type nickel iron oxide. In September 2020 he started his integrated MSc+PhD as a part of the Center for High Entropy Alloy Catalysis, where he is currently mapping synthesis methods for high entropy alloys, as well as studying their formation mechanisms.

Laura Glei Graversen
Laura began working with our group in February 2021 for her BSc project and is now enrolled in the integrated MSc+PhD program to study the formation of niobium-, molybdenum-, and tungsten oxide nanoparticles. She focusses especially on how the employed solvent influences particle size and structure.

Master Students:

Frederik is working on implementing Reinforcement Learning into the characterization of nanostructures from Pair Distribution Function data.

Ulrik Friis-Jensen
Ulrik develops generative machine learning models, aiming to characterize metal oxide nanoparticles.
