Overview

This three-year salaried PhD position at Justus Liebig University Giessen, Germany, focuses on the OREOcube and Exocube experiments aboard the International Space Station. The successful candidate will investigate how radiation alters organic molecules using advanced spectroscopy and laboratory techniques. The work bridges astrochemistry, space physics, and molecular chemistry, contributing to understanding prebiotic chemistry in space environments. The position is ideal for candidates with a strong background in experimental physics or chemistry and an interest in space research. The project is part of a broader effort to explore the origins of life and molecular processes in space.
