Leoni received her Bachelor’s degree in Biology from the Technical University of Darmstadt, where she investigated immunogenicity of cell death at the GSI Helmholtz Center for Heavy Ion Research for her thesis. In her Master thesis in the group of Dr. Tatarova, she explored histopathology staining methods and bioinformatic tools to study resistance mechanisms in the breast cancer tumor microenvironment. After receiving her Master degree, Leoni continues with her project as PhD student in the lab with a DKTK CORTEX fellowship aiming to develop an analytical platform to predict immunotherapy response and resistance in breast cancer patients. Leoni joined the laboratory in September 2023.
