M. Sc. Ellen Armella Bisle
Ellen Bisle studied Molecular Medicine from 2016-2019 and Molecular and Translational Neuroscience from 2019-2021 at the University of Ulm. Her bachelor's thesis dealt with the influence of traumatic childhood experiences on hair cortisol, taking genotype into account. She wrote her master's thesis at Boehringer Ingelheim in Biberach on mitochondrial glutamate transporters and their influence on glutamate homeostasis and the bioenergetics of astrocytes. During her bachelor's degree, she also obtained a certificate of competence in accordance with § 11 of the German Chemicals Prohibition Ordinance. As part of her scholarship at the German National Academic Foundation from 2017-2021, she took part in the summer academies ‘Neurodegenerative Diseases’ and ‘Molecular Psychotraumatology meets Molecular Nutritional Physiology: Can a healthy diet help us stay mentally healthy?’. She has been doing her doctorate at the Department of Clinical & Biological Psychology at Ulm University since 2022. Her research focuses on the interaction of gut bacteria, the metabolome and biological changes in people with depression. In addition, the effects of therapy on biological processes are examined.
