Sascha Feldmann

Postdoctoral opening in ultrafast spectroscopy and excited-state dynamics in energy materials within the Marie Curie Network LEAPS-ULTRAFAST . The project is a 3-year postdoc hosted through a collaboration between SwissFEL / Paul Scherrer Institute and the Laboratory for Energy Materials at École Polytechnique Fédérale de Lausanne (EPFL) . The research focuses on halide perovskite semiconductors and nanocrystals , including fully molecular, inorganic, and hybrid/halide perovskite systems. Possible directions include chirality , magnetism , spin-photophysics , local symmetry, confinement, and how composition and structure shape photoexcited-state dynamics. The project combines two complementary experimental environments: ultrafast X-ray absorption/emission/diffraction at SwissFEL Alvra and ultrafast magneto-chiroptical spectroscopy plus materials synthesis/characterization at EPFL . The fellow is expected to propose an independent research direction and develop a strong proposal that makes full use of the available facilities. The post is especially relevant for candidates with interests in physics , chemistry , and materials science , particularly those working on spectroscopy, nanomaterials, energy materials, or light-matter interactions. Funding is through the Marie Curie Network ; the position lasts up to 3 years . The post mentions access to major facilities and advanced laser systems, but does not specify a stipend amount in the announcement. Applications close on 2026-09-30 , and the fellowship is expected to start at the beginning of 2027 . Interested applicants can also contact the supervisors informally with a CV, publication list, and research proposal idea before submitting the formal application.
