– TRADITION SINCE 2014 –
Note: This is a regularly updated, internal website by members of the Applied Zoology group at the Technische Universitaet Dresden. The official website, less often updated, is here. Our lab is also involved in the Dresden International PhD Programme (DIPP) and has a page there.
In our lab, we seek answers to fundamental zoological questions, such as determinants of male (in)fertility, the role of mitochondria in metabolism, phenotype and evolutionary change. We also study the genetics and material properties of the insect skin.
We aim to become an internationally recognised lab for combining evolutionary with molecular and microscopy approaches in three areas: 1) metabolism and metabolic diseases, 2) sperm biology and male infertility, and 3) bioprospecting. Mainly using Drosophila, we link sperm physiology with environmental and mitochondrial variation to reveal causes of sperm dysfunction in vivo, address problems related to metabolic diseases and inform material science and applied areas by testing hypotheses about the molecular biology and function of the insect cuticle.
