Project: “Tame Voices: The Impact of Human Selection on the Vocalization and Larynx of Domesticated Animals”

Throughout all projects within my bachelor and master program I always chose to work on domesticated animals. For my bachelor thesis in Zoology I analysed high-speed recordings of chicken (Gallus gallus domesticus) drinking and feeding. Within my master thesis in Behavioural-, Neuro- and Cognitive Biology I connected my interest in domestication with bioacoustics for the first time and worked on acoustic communication in human-dog dyads.  

My PhD project focuses on the differences and changes in the domesticated animals voice and larynx in comparison to their wild ancestors. My model species range from rats (Rattus norvegicus domesticus) to cats (Felis silvestris catus) and dogs (Canis lupus familiaris). Through methods ranging from µCT scans of larynges to the analysis of acoustic parameters I hope to gain insight on the impact domestication had on the vocal behaviours and communication abilities of domesticated animals.
