The "Physics of molecular and biological matter" group at the University of Tübingen is seeking a highly motivated PhD student or doctoral candidate to join their research on protein dynamics. The group, led by Prof. Dr. Dr. h.c. Frank Schreiber, specializes in the physics of molecular and biological matter, employing advanced X-ray and neutron scattering techniques. Their research spans materials for photovoltaics, proteins in solutions and at interfaces, complex nano-structured materials, and the development of machine learning tools for efficient experimental data analysis. The successful candidate will focus on understanding the structure and dynamics of protein molecules in concentrated solutions. The project involves the use of Small-Angle X-ray Scattering (SAXS), X-ray Photon Correlation Spectroscopy (XPCS), Quasi-Elastic Neutron Scattering (QENS), and Dynamic Light Scattering (DLS) to investigate protein behavior. The role includes sample preparation, preliminary characterization using laboratory X-ray setups, participation in experiments at leading large-scale X-ray and neutron facilities (such as PETRA III, EuXFEL, ESRF, and ILL), and data analysis. The candidate will also have opportunities to present results at conferences and in scientific publications. Applicants should possess a Master’s degree in physics or chemistry (or equivalent), demonstrate interest in materials science, and have strong written and spoken English skills. Experience with programming (especially Python), practical laboratory skills, and enthusiasm for experimental work are highly valued. The ability to work independently and as part of a team is essential. While knowledge of German is not required, it is considered an advantage. The position is funded at the E13 TV-L salary scale (50-75%) for three years and offers the chance to work in an international, collaborative environment with access to state-of-the-art laboratories and equipment. The University of Tübingen is recognized as a University of Excellence in Germany, with a vibrant academic community and a commitment to diversity and equal opportunity. The city of Tübingen offers a rich student life, cultural events, and beautiful surroundings. To apply, candidates should send a single PDF file containing a cover letter, CV, and transcript of records to the specified email address. The position is available immediately and will remain open until filled. For further details about the group and research activities, visit the group website or the DAAD application page .
