Fabienne Ziadi-Künzli

Postdoctoral Researcher

As a passionate fish biologist, I have a general interest in the biodiversity, ecology, and evolution of coral reef fishes and their bigger cousins’ sharks. I am particularly interested in the interplay of species-specific life history and behavior of fishes and how these characters can have implications for conservation and sustainable resource management in order to maintain healthy and functional marine ecosystems.

My current research at OIST focuses on the evolutionary transformation of the locomotor system and anatomical elaborations of the pectoral fin of amphibious mudskippers (oxudercinae gobies) using modern imaging techniques such as x-ray micro-computed tomography. Specializing in 3D imaging and subsequent data segmentation has facilitated collaborative projects encompassing research questions related to organismal biology, morphological diversification, or ontogenetic development involving bony fishes as well as invertebrates. I further study the cryptic deep-sea shark community of the Ryukyus Archipelago and mainland Japan by combining comparative morphology and phylogenetics in order to understand their biodiversity and endemicity.

In my free time, you can find me training horses (natural horsemanship) and practicing Karate (instructor, 3. Dan).
