Zoology and Developmental Biology
The Department of Zoology and Developmental Biology studies the genetic basis of tissue and organ development in the model organism Drosophila melanogaster. We focus on deciphering the molecular and developmental processes that lead to the formation of the muscles, heart and excretory system. In addition to our basic research, we work together with human geneticists to establish Drosophila models for inherited human heart diseases (cardiomyopathies).
Research topics
- Animal models for human hereditary diseases
- Organ differentiation and function
- Genetic regulation of developmental processes
Model systems
- Drosophila models for human diseases
- Heart development and function (cardiogenesis)
- Cell-cell fusion (myogenesis)
- Endomembrane dynamics in Drosophila cells
- Extracellular matrix of the heart
Methods
- CRISPR-Cas9, transgenic Drosophila
- Molecular- and classical genetics, protein networks, proteomics
- Heart performance measurements, heart beating, life span, locomotion)
- Developmental biology methods, immunostaining, developmental expression profiling
- Confocal laser scanning microscopy, Light-Sheet-microscopy, DNA-Paint
- Transmission and scanning electron microscopy
