Research topic

I am working on the development and establishment of a lung cancer model in Drosophila. The aim is to understand the molecular and genetic basis of tumor formation and progression. Overexpression of cancer-associated genes (e.g. EGFR, Ras, MAPK) in the tracheal epithelium can induce cancer-like phenotypes like epithelial meta- and hyperplasia. I am investigating this phenotypes by microscopic analysis for differences on a cellular level (quantification of epithelial thickness, cell and nucleus size and number, cell connections and cell shape…) and by other methods (IHC, qPCR) to investigate the tumor formation on a translational and transcriptional level.

Research topics

Based on results of my phD thesis I am investiganting the epithelial immune response in the fruit flys intestine. Especially the interaction between the microbiome and the host is not fully understood yet. Beside the classical antimicrobial peptide response via NF-kB pathways (Toll & Imd), I am interested in the DUOX response mechanisms that not only effects invading pathogens but even also the own microbiome. I want to understand how the host-microbiome-homeostatis is staying in balance.

Furthermore I am working with the airway epithelium of Drosophila. I am investiganting different epithelial phenotypes in the fly that model lifestyle diseases like  Asthma, COPD & lung cancer and try to investigate the underlying cell signalling mechanism that may cause the typical disease-like phenotypes. One major aspect is to test the influence of human suceptibility genes in the fly model to further investigate targets for a better treatment of this diseases.

Marine algae, which contain many biologically active compounds are my target of study. I endevaor to reveal algal extractions that have functional ingridients and to shed light on the mechanism of action of these algal extractions using Drosophila melanogaster as a read-out model. I am carrying out life span experiments with different concentrations of the corresponding algal extracts and a series of physiological experiments. I intent for evaluating which organ is the target of this intervention using tissue-specific RNAi experiments and looking into different genes, which show a clear age-associated increase increase in expression level.

Research topic

I am highly fascinated by the effects of nutritional stress on the immunocompetence of animals. Using Drosophila melanogaster as a model, I work on deciphering the impact of different dietary compositions in terms of protein to carbohydrate ratios. Therefore, I examine various phenotypic and genotypic immune defense parameters, like survival ability on facing a pathogen, pathogen clearance and expression of genes involved in the immune system. Furthermore, I plan to extend my work to look for the existence of lifelong or trans-generational memory of nutritional stress and response to secondary stress encounters.

I am working on the generation of tumor models in the tracheal system of Drosophila for the identification of new targets for lung cancer treatment. Therefore, I manipulate different proto-oncogenes as well as tumor-supressor genes or combinations of both to generate tumor-like phenotypes of the tissue. By using these models, I am searching for unkown single compounds or combinations of compounds in different concentrations as a new treatment option.

Research topic

I’m interested in using humanized Drosophila models to study metabolic diseases such as diabetes and obesity. Firstly, I produce humanized Drosophila suited for studying diabetes and obesity in the fly based on CRISPR/Cas9 technology and Gal4/UAS system. I will use the newly generated tools to experimentally interfere/induce obesity in the fly, then have a depth characterization of the influence of manipulation of hormonal signaling on diabetes and obesity.
