Applied Zoology at Dresden


Our research revolves around two fundamental zoological issues and their societal significance. i) molecular-physiological mechanisms, and evolutionary consequences of male (in)fertility and sperm function, and ii) the role of mito-nuclear interactions on metabolism, the phenotype and evolutionary change. Want to join us?

Disclaimer: This website by members of the Applied Zoology lab at the Technische Universitaet Dresden is regularly updated but is not the official university website (which is here and which cannot frequently be updated for technical reasons).

Mission Official

We aim to become an internationally recognised lab for combining evolutionary with molecular and microscopy approaches in research on mito-nuclear interactions and on sperm biology and male infertility. 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.

See here for details of our research and here for our publications. We aim at high representation in the press. Our current teaching areas are here. Contact us.

Not Applied Zoology…


… but amazing: Dresden artist Manaf Halbouni created an image of the Unimaginative: what it would look like if Dresden, or the Frauenkirche, had to be protected from war and destruction.

Outside regular lecture times: Please email Professor Reinhardt for an appointment (Contact).
