Postdoctoral Scholarship in Transmission Electron Microscopy and 4D-STEM for Soft Materials Stockholm University in Sweden

The Department of Chemistry at Stockholm University is offering a postdoctoral scholarship in transmission electron microscopy, with a focus on developing methods for 4D-STEM and scanning electron diffraction (SED) applied to soft and beam-sensitive materials, such as biopolymer composite materials. The project aims to advance techniques for 3D reconstruction of SED data, enabling the study of hierarchical organization in biobased composite materials at the nanoscale.

Research in the department spans analytical, physical, materials, inorganic, and organic chemistry, with a strong emphasis on sustainable chemistry and advanced analytical methods. The department boasts state-of-the-art research infrastructure and a vibrant international environment. The Willhammar Group, led by Associate Professor Tom Willhammar, specializes in electron microscopy and materials characterization, providing opportunities to work with cutting-edge techniques and collaborate with leading international groups.

The successful candidate will develop protocols for data collection and analysis, interpret large datasets, and contribute to understanding the properties of soft and beam-sensitive materials. The project is ideal for candidates with a PhD in Chemistry, Physics, Biology, or related fields, and experience in (S)TEM or scattering-based characterization techniques. Familiarity with advanced (S)TEM methods such as 4D-STEM or SED, and skills in scientific programming, are advantageous. Strong collaborative, communication, and organizational skills are essential.

This is a scholarship-based position (not formal employment), funded for 1+1 years. The application deadline is January 20, 2026. Applicants should submit their application to Assoc. Prof. Tom Willhammar, including a cover letter, CV, research proposal, and contact details for two references. For more information, visit the Willhammar Group webpage or the official announcement.
