Below is a summary of the main projects I am currently working on.
Effect of early experience on social and exploratory behaviour
I aim to understand how differences in early experiences can affect an individual’s ability to coordinate effectively with group members later in life and whether and if so, how these differences ultimately affect individual fitness. I am currently studying these questions in the domestic chicken (Gallus gallus domesticus) and combine direct observations, experiments and data collected remotely with state-of-the-art techniques in computer vision and machine learning for data pre-processing and analysis.
As part of this project I further study the use of acoustic cues to coordinate hatching and how vocal signals facilitate communications with parents and siblings when still within the egg. For this study I use both lab experiments with domestic chicken as well as field studies with Pūkeko – Australasian swamphen (Porphyrio porphyrio melanotus).
