– TRADITION SINCE 2014 –
Our research revolves around a fundamental biological issue – reproduction, why it differs between individuals, and its societal significance. Specifically, we do research on i) molecular-physiological mechanisms and evolutionary consequences of male (in)fertility and sperm function, ii) the role of mito-nuclear interactions on metabolism, the phenotype and evolutionary change, and iii) hormonal control of spermatogenesis.
AZ = E*M3 : Applied Zoology combines molecular, metabolic and microscopy with evolutionary approaches. We are aiming to become internationally recognised in sperm biology and mito-nuclear research mainly using Drosophila, nationally for hormonal control of fish spermatogenesis, and contribute to sex chromosome research. Want to join us? 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.
