Research Interest

My research interests centre on acoustic communication in animals, with a particular focus on fish. I investigate various aspects of how fish produce, perceive, and use sound, including:

  • Intraspecific and interspecific communication

  • Relationships between acoustic signals and behaviour

  • Environmental and anthropogenic influences on communication and behavioural responses

  • Morphology and function of sound-producing structures

  • Mechanisms of sound perception (auditory periphery and hearing sensitivity)

  • Methods and analysis of acoustic signals

My current research focuses on the functional morphology of auditory structures and the inner ear in fishes (teleosts), in particular, otophysan species. The study explores how key components of the auditory system, like the swim bladder, the Weberian ossicles, and the otoliths, interact to facilitate sound perception and transmission. To address these questions, we employ synchrotron-based tomographic imaging, which allows for highly detailed, non-invasive visualization of internal structures. By applying time-resolved 4D tomography, we can capture and analyse dynamic movements and functional relationships in real time. This innovative approach represents a major methodological advancement, providing unprecedented insights into how the hearing structures of fishes contribute to the function of the inner ear and, more broadly, to the evolution of vertebrate auditory systems.
