Hannah Keppler's academic background is in psychology, which she studied at the University of Ulm from 2015 to 2018. As part of her bachelor's thesis, she investigated the molecular genetic basis of economic decision-making processes. Following a research internship in the genetics laboratory of the Department of Molecular Psychology, she decided to focus on an interdisciplinary biopsychological approach with the Master's programme in Molecular and Translational Neuroscience (2019-2021, Ulm University). In her master's thesis, she focused on the immunocellular expression of glycolytic genes in the context of traumatic childhood experiences. During her master's thesis, she was employed as a student assistant at the Department of Clinical and Biological Psychology.
Since December 2021, she has been pursuing her doctorate at the Chair of Clinical and Biological Psychology at Ulm University. Her research is oriented towards two primary domains: firstly, the alterations in the immunocellular energy metabolism of depressed patients and secondly, the impairment of DNA integrity in the context of traumatization.
