The Fritz Haber Institute of the Max Planck Society for the Advancement of Science ( with its approximately 470 employees is one of the most internationally renowned research institutes in its field. The institute conducts fundamental research to understand chemical and physical processes at surfaces, interface clusters and nanostructures. Our scientists conduct cutting-edge research on historic grounds, which is unique worldwide.

A joint PostDoc position is available within the Winter Research Group at the Fritz-Haber-Institute Berlin (FHI) and the Wilkinson Group within the Institute for Electronic Structure Dynamics at the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB).

Postdoctoral position (m/f/d) Time- and energy-resolved photoemission spectroscopy of liquids

The postdoctoral research project will focus on developing a molecular-level understanding of the ultrafast energy, charge, and mass transfer processes that occur following photoexcitation of (bio)chemically relevant aqueous solutions. These processes will be studied using time- and energy-resolved liquid-jet photoemission spectroscopy techniques, employing modern laser-laboratory- and accelerator-based ionizing radiation sources. The research will primarily be performed at the state-of-the-art, ultrashort-pulse extreme ultraviolet and soft-X-ray laser facilities (ULLAS and LIDUX) at the Wannsee campus of HZB, where a range of high harmonic generation beamlines and liquid jet spectrometers are in operation. Periodic work at FHI and at X-ray-light-source user facilities is also envisioned. The outcomes of this research are expected to lead to an improved understanding of fundamental chemical, photodamage, and photoprotection mechanisms of chemical species in their natural or applied aqueous environments.

    Your profile

    Candidates must have a doctoral degree in physics, chemistry, or a related discipline and have direct and demonstrable experience with at least two of the following research areas:

    • Ultrashort-pulse laser systems

    • High-vacuum instrumentation
    • In-vacuum liquid microjet techniques
    • Programming and data analysis in any common framework (Python, Igor Pro, Matlab, Origin …)

    Considered candidates must be able to work independently and as part of an international team. A working knowledge of the English language is also essential.
