Stockholm University is a leading European university in one of the world's most dynamic capitals. The University has more than 33 000 students, 1600 doctoral students and 5500 staff active within science, the humanities and the social sciences.

The Department of Physics is one of the biggest departments within the Faculty of Science and supports a broad range of basic research in experimental and theoretical physics. It has about 240 employees of which 95 are PhD students. Many have been internationally recruited. The Department is part of the AlbaNova University Center, which apart from the Department of Physics houses the Department of Astronomy (Stockholm University), the Physics Departments and the Division of Theoretical Chemistry at the Royal Institute of Technology (KTH), and the Nordic Institute for Theoretical Physics (Nordita).

Research area

The Department of Physics have a postdoctoral scholarship position available for an outstanding individual for studies in the area of liquids and glasses. The project is multi-disciplinary and the objectives are to develop liquid jet sample environment for x-ray scattering experiments in vacuum, coordinate international research collaborations and perform multi-disciplinary experiments at synchrotron and XFEL facilities, analyze experimental data using object-oriented programming and machine-learning algorithms. The host laboratory offers state-of-the-art equipment and expertise in X-ray diffraction, X-ray spectroscopy, X-ray pump-probe and High Harmonic Generation experiments.

The scholarship position is placed at the Department of Physics and the Postdoctoral Fellow will work as part of the group of X-ray Science of Liquids and Surfaces, XSOLAS ( The group activity is related to investigating the structure and dynamics of water and aqueous solutions on a molecular level, as well as studying ultrafast chemical reactions at surfaces and catalysis. The focus of the project is to study the dynamics of aqueous solutions in the liquid and glassy phase using X-ray Photon Correlation Spectroscopy (XPCS). The experiments will take place at national and international X-ray synchrotron (such as MAXIV, PETRA III, ESRF) and free electron lasers (such as Eu-XFEL, FERMI, LCLS, SACLA, PAL), as well as at in-house laser setups at Stockholm University.

Qualification requirements

Scholarship for conducting postdoctoral studies can be awarded for up to two years within five years after PhD or equivalent.

A suitable background is a Ph.D. in physics, chemistry or biophysics with experience in x-ray studies at synchrotrons and free-electron lasers or laser physics and vacuum technology. The applicant should have the ability to work both independently and in a group, and be able to travel abroad for extended periods of time (2–10 weeks).

The assessment is based on documented experimental knowledge relevant to the area, knowledge of and experience in instrumentation and experimental methods, analytical skills, and personal commitment. Strong motivation is considered a key component for a successful outcome of the postdoctoral research. Applicants are invited to enclose documents certifying qualifications and competences relevant to the application. Letters of recommendation and interviews will be used to assess the applicant's qualifications.

The scholarship

The postdoctoral scholarship is for one year with the possibility of extension for another year. Start date as soon as possible or per agreement.

Stockholm University strives to be a workplace free from discrimination with equal opportunities for all.
