Jessica is a German researcher from a small village in the west of Germany. She received her bachelor’s and master’s degree in Physics from the Johannes Gutenberg-Universität Mainz. During her studies, Jessica spend more than two years at The University of Gothenburg in Sweden, were she also conducted both, her bachelor’s and master’s thesis.
During her time in Gothenburg, Jessica specialized in collinear laser spectroscopy of negative ions. She developed a graphene-based neutral particle detector offering new possibilities for collinear spectroscopy of negative ions in the UV range, which was later applied in the electron affinity measurement of astatine at ISOLDE, CERN. Driven by her keen interest in atomic physics, Jessica dedicated her master’s thesis to the resolution of hyperfine structure in a photodetachment cross section measurement and worked on applications of negative ions at the AMS facility VERA in Vienna. Before starting her PhD, she designed a new neutral particle detector for isotope shift measurements in the electron affinity of chlorine isotopes at ISOLDE.
With her position in the LISA program, Jessica is able follow her interests in atomic and nuclear physics and to evolve as a researcher in an outstanding network. She is excited to learn new spectroscopy techniques and to contribute to atom-at-a-time laser spectroscopy of the heaviest actinides at GSI.
When not in the lab, Jessica is engaged as a lifeguard and enjoys hiking, playing and listening to music.
