Research interests
My current research focuses on the functional morphology in the ear of teleost fishes with a main interest in the structure-function relationships between otolith morphology, sensory epithelia, ancillary auditory structures, and hearing abilities.
For my studies on fish hearing, I apply electrophysiological methods to evaluate auditory abilities in terms of the detectable frequency range and auditory sensitivities. From a methodological viewpoint, I am especially interested in applying imaging techniques such as electron microscopy and confocal microscopy (in combination with immunohistochemistry), micro-computed tomography, synchrotron radiation and neutron imaging, and 3D reconstructions based on X-ray imaging and serial histological sectioning.
As I am also working at the interface of biology and paleontology, I am involved in studies dealing with the evolution of otolith shape diversity in teleost fishes. My research activities in functional morphology therefore aim to identify adaptations or specializations—where existent—which may help to interpret fossil otoliths from a physiological view point because otoliths are the only fossil remains of teleost ears.
In order to better understand the emergence of solid otoliths in teleost fishes contrasting the numerous tiny otoconia found in the ears of most other vertebrate groups and the evolution of otolith shape diversity, my current work concentrates on the characterization of the basics of otolith motion in-situ and factors like otolith mass and shape influencing this motion. These basic data are implemented in a recent cooperative project in advanced modelling of otolith motion in the fish ear. In addition, I am also involved in studies which aim to identify environmental factors and the amount of phenotypic plasticity influencing brain (region) size and shape in poeciliid fishes.
