Since the first of August, Paul Klar has held the new Researcher/Senior Researcher position in Materials Science Mineralogy in our department. Paul is a proven expert in crystallography and electron diffraction. He studied geosciences (BSc) and Materials Science (MSc) in Munich and went to the Universidad del País Vasco in Bilbao as a PhD student where he completed his dissertation with honors in Physics in 2018. As a Postdoctoral Fellow, Paul conducted research in the Department of Structure Analysis at the Institute of Physics of the Czech Academy of Sciences in Prague on the resolution and refinements of crystal structures based on X-ray and electron diffraction experiments. He is heavily involved in the development of this new and innovative area of crystallography, which involves the refinement of crystal structures using dynamic electron diffraction data. We are very pleased that Paul will develop his excellent methodological and theoretical approaches to research and teaching in our department and substantially strengthen us with valuable expertise in materials science.
