Unravel Resilience - Using Multi-Omics Integration to explore the Molecular Background of Stress Resilience 

Resilience is the ability to cope with stress or to quickly recover to pre-crisis state after being exposed to extreme stress. As the human mental status is highly diverse, there are presumably many different molecular mechanisms underlying resilience. The main goal of this project is the identification of common molecular patterns between resilient individuals by analyzing and integrating various omics levels, e.g. transcriptomics, proteomics, methylomics and metagenomics. By subsequently selecting important features within the large amount of data, we aim to give a less complex view on the dynamic process of resilience. This work is funded by the Leibniz Institute for Resilience Research (LIR) and in collaboration with the  Frauenhofer ITWM. MARP and LORA studies from the LIR.

Optimization of the Calcium Imaging Analysis Pipeline 

Calcium Imaging Analysis enables researchers to track the activity of hundreds and thousands of neurons within the brains of living animals. However, analyzing this huge amount of data raises some difficulties. Together with the group of Prof. Dr. Albrecht Stroh and in collaboration with the Fraunhofer ITWM, we are following the goal of improving and accelerating the analysis of calcium imaging data, starting with the automatic marking of neurons in the generated image files using deep learning. By optimizing and simplifying the application through user-friendly interfaces of the entire analysis pipeline, the effort and time required for Calcium Imaging Analyses can be drastically reduced and will also be less dependent on personal decisions.

Molecular Changes after Different Sport duration in Alzheimer’s disease 

There are several studies that investigate the effect of sport on neurodegenerative disease. However, the benefits of sport concerning the time and duration are highly controversial. In this study, the aim is to find differences in gene expression and splicing between transgenic (5xFAD) mice modeling Alzheimer’s disease and wild-type mice after two different sport duration.

The Difference of Aging Phenotypes in Drosophila melanogaster 

The underlying causes for the physiological aging of an organism are very diverse. An essential feature of ageing is transcriptional change. In order to find evolutionary conserved transcriptional patterns involved in the prolongation of life and/or health span, the gene expression profiles of fruit flies with different aging profiles are analyzed and compared to human achievements. This approach might provide new insights into natural resistance to age-related changes.
